The same is true for the mods. Mods don't own subreddits, the community does. If they want to close down communities that aren't theirs, why not just quit Reddit? They are free to stop moderating.
No, just the ones that people are strongly motivated to brigade, and ones where I saw discussion of discord groups where links to such polls were posted to mobilize brigaders. But none of that should matter. If you claim your poll is representative, you need to demonstrate it. Don't make claims that outpace your evidence. It's not that hard.
That is (1) not true and (2) meaningless given most of those polls were brigaded by a small set of vocal whiny users voting in subreddits they aren't even involved in (3) even given both if those, I doubt you can find a poll for a large subreddit that shows even 10% of users supporting a blackout.
r/freemagic users who were banned from r/magicTCG talked about voting in the r/magicTCG poll. Apparently, mods of r/tennis posted in a Discord asking people to come help and vote to support the blackout as well. A lot of polls were mentioned in r/ModCoord which biases strongly in favor of the blackout. There’s much more incentive to brigade on the blackout side since users who don’t care about the subs in question lose nothing by those subs going private.
Eh, I gave you the clear out under #3 where you could show that these blackouts were really the will of the people. You haven't done that, if your strongest argument is about "oh, prove there was brigading", I think we're at the point where, at best for you, any polls are basically just meaningless (if they were meaningful you could use them under point #3 to refute me).
I think the larger issue is now the blackout is still continuing the addicts are needing their fix.
