We’re thinking more about this now that our API is nearing.
In the meantime, note that you can block any member from following you or posting comments on your content (look for the Flag icon on the member’s page).Wes Ballls commented
Planned since 2013? C'mon, guys! Sort this shit out. What social networking site doesn't have privacy features? Ridiculous.
We have considered a few options in consultation with members, and our solution to preventing members posting comments (and removing all comments from a member) is to Block the member on their profile page.
Blocking was recently upgraded so if you block a member, their comments are removed from all of your content, for you and anyone who visits it.
We’re happy with the 15-minute edit window on comments, and in extreme cases you can use the report function to have your own comments removed beyond this window.
At this time there are performance and cacheability impacts of blocking members everywhere that preclude us from doing this. In the future we would like to address this better.
