I’m surprised that no one addressed this point directly. Is there any substance to the user’s complaints?
If so, that’s a bit worrying.
If users in general on your forum are using the flagging system as a “downvote” button, perhaps some forum-wide education about what it’s actually for would be helpful.
If you have users who are deliberately abusing the flag button to grief or censor other users, you need to make it clear to them that this behavior is not acceptable. It they persist, use the moderator tools, including:
- TL-level locks
Depending on how egregiously abusive they are/how resistant they are to modifying their behavior.
If you have abusive flaggers, they won’t stop with a single user. They’ll either collect enough support to flag at the higher threshold, out move on to other victims. In the meantime, you’ve made it harder for valid flags to hide problematic posts.
