I found a way for some forums to hide content from users I don't like and/or I can't block for some reason using uBlock Origin - when they're moderators or admins.I banned myself from a movie forum because that got under my skin.
For a phpbb3 it's a little tricky but generally goes like this:
Code:
www.domainname.net##.post.has-profile:has([id^="post_hidden"][class="ignore"])
Code:
www.domainname.com##.responsive-hide [class^="username"]:has-text(Zeroadhesion):upward(.post)
For an IPB forum:
for ignored users (bc ignored content is still displayed, though not fully):
Code:
www.kaldata.com##.ipsComment_ignored
for "advanced" users like admins or moderators:
Code:
www.kaldata.com##ipsProfile_370533
That way if someone's bothering you, you can trash them, even if they're the admin of the forum.
The good news is that I haven't come across any toxic users here, so I never needed to search for such ways to block users on this forum.
