It's meta. You can't make self-moderated threads there.

Also the rules are quite clear imho. No spamming, no merit begging. Posting your own records and records of other users.

If you think some users are spamming the thread or fishing for merit use the report function and report it to the mods. They will handle the issue.

I don't see the reason to make another drama about this. Everyone knows there are certain accounts just posting for merits (not only in that thread, but in many threads). Just don't reward them for their shitposts, use the ignore function and move on.
