Instagram today revealed a series of changes that makes it easier to moderate content on your account. Including, at long last, the ability to delete comments in bulk.

While the company has been experimenting with the option for some time, today it’s rolling out to users in general. In order to use the bulk-delete comments on iOS, tap on a comment, and then the dotted icon on the top right. Tap ‘manage comments‘ and pick up to 25 comments to delete at once, or tap ‘more options’ to block or restrict accounts. On Android, you can simply tap and hold to select multiple comments. You can then tap on the dotted icon to block or restrict accounts.
