Mitigation of bullying and objectionable content

1. A method comprising:

receiving, from a first computing device associated with a first user account, a request to restrict presentation of content having a characteristic and received from a second user account;

receiving, from a second computing device associated with the second user account, an item of content having the characteristic;

sending, to the first computing device associated with the first user account and based at least in part on the request to restrict presentation, a first instruction to present a first representation of the item of content; and

sending, to the second computing device associated with the second user account, a second instruction to present a second representation of the item of content, the second representation of the item of content being different than the first representation of the item of content.

2. The method of claim 1 , wherein the characteristic comprises being at least one of associated with or addressed to the first user account.

3. The method of claim 1 , wherein the first representation of the item of content comprises an indication of existence of the item of content and a control usable to cause presentation of the item of content by the first computing device.

4. The method of claim 1 , wherein the second representation of the item of content represents the item of content as though visible to one or more other user accounts.

5. The method of claim 1 , wherein the item of content comprises a comment by the second user account associated with another item of content published by the first user account.

6. The method of claim 5 , further comprising sending, to the first computing device, an instruction to present a selectable control usable to at least one of approve or disapprove the comment.

7. The method of claim 6 , further comprising:

receiving, from the first computing device, an indication of selection of the selectable control to disapprove the comment; and

based at least in part on receiving the indication of selection of the selectable control to disapprove the comment, at least one of:

sending, to the first computing device, an instruction to cease presenting the first representation of the item of content; or

refraining from sending the second representation of the item of content to a third computing device associated with a third user account.

8. The method of claim 6 , further comprising:

receiving, from the first computing device, an indication of selection of the selectable control to approve the comment; and

based at least in part on receiving the indication of selection of the selectable control to approve the comment, at least one of:

sending, to the first computing device, an instruction to present the second representation of the item of content; or

sending, to a third computing device associated with a third user account, an instruction to present the second representation of the item of content.

9. A system comprising:

one or more processors; and

computer readable media storing instructions that, when executed by the one or more processors, cause the system to:

receive, from a first computing device associated with a first user account, a request to restrict presentation of content having a characteristic and received from a second user account;

receive, from a second computing device associated with the second user account, an item of content having the characteristic;

send, to the first computing device associated with the first user account and based at least in part on the request to restrict presentation, a first instruction to present a first representation of the item of content; and

send, to the second computing device associated with the second user account, a second instruction to present a second representation of the item of content, the second representation of the item of content being different than the first representation of the item of content.

10. The system of claim 9 , wherein the item of content comprises a message from the second user account to the first user account.

11. The system of claim 10 , wherein the first instruction to present the first representation of the item of content comprises an instruction to present an indication of existence of the message in a secondary inbox.

12. The system of claim 11 , the instructions further causing the system to:

receive, from the first computing device, a request to view the message; and

send, to the first computing device, an instruction to present:

the message; and

a control usable to at least one of:

unrestrict presentation of content received from the second user; or

delete the message.

13. The system of claim 12 , the instructions further causing the system to refrain from sending, to the second computing device, a notification that the message has been presented at the first computing device.

14. One or more non-transitory computer readable media storing instructions that, when executed by one or more processors of a computing device, cause the computing device to:

receive, from a first computing device associated with a first user account, a request to restrict presentation of content having a characteristic and received from a second user account;

receive, from a second computing device associated with the second user account, an item of content having the characteristic;

send, to the first computing device associated with the first user account and based at least in part on the request to restrict presentation, a first instruction to present a first representation of the item of content; and

send, to the second computing device associated with the second user account, a second instruction to present a second representation of the item of content, the second representation of the item of content being different than the first representation of the item of content.

15. The one or more non-transitory computer readable media of claim 14 , wherein the item of content comprises a comment by the second user account associated with another item of content published by the first user account.

16. The one or more non-transitory computer readable media of claim 14 , wherein the first representation of the item of content comprises an indication of existence of the item of content and a control usable to cause presentation of the item of content by the first computing device.

17. The one or more non-transitory computer readable media of claim 14 , wherein the second representation of the item of content represents the item of content as though visible to one or more other user accounts.

18. The one or more non-transitory computer readable media of claim 14 , the instructions further causing the computing device to:

receive, from the second computing device, input comprising a portion of an identifier of the first user account;

determine that the portion of the identifier of the first user account is less than a threshold level of similarity to the identifier of the first user account; and

output, based at least in part on the portion of the identifier of the first user account being less than the threshold level of similarity, one or more candidate user accounts, the one or more candidate accounts omitting the first user account.

19. The one or more non-transitory computer readable media of claim 18 , wherein the threshold level of similarity is based at least in part on the request to restrict presentation of content having the characteristic.

20. The one or more non-transitory computer readable media of claim 14 , the instructions further causing the computing device to:

receive, from the second computing device, input comprising a portion of an identifier of the first user account;

determine that the portion of the identifier of the first user account meets or exceeds a threshold level of similarity to the identifier of the first user account; and

output, based at least in part on the portion of the identifier of the first user account meeting or exceeding the threshold level of similarity, one or more candidate user accounts including the first user account.
