Well, I'm for this move. The why is obvious, as you've covered it in the post already.
I would also like to voice support for a couple ideas from previous comments
First, that previous posts stay up, and locked, so that people can still see that the issues were.
Second, that y'all consider the possibility of an FPT (frequently power tripped) thread at some frequency where folks can still hash out the common subjects. This and the mod abuse C/ are valuable pressure relief valves. I worry that a total banning of "frequent fliers" (sic) might have effects down the road.
I know that's extra work for mods, so it's definitely a big ask, but lemmy does need places where disgruntled users can complain. Having multiple places is better because one community would get swamped if they're the only place people can go for specific complaints.
