It doesn’t seem like you’re being banned for saying your opinion freely.
It seems like you’re having posts removed because you don’t follow the rules and when someone points it out you choose to fight about it instead of fixing the problem on your end.
That event, nine days ago in your public modlog, took place on the lemmy.world server and you’re registered on lemmy.wtf. Changing servers won’t remove the world/c/asklemmy mods’ ability to enforce their rules.
Unless you’re talking about something else it seems like the problem here is you. Change your behavior or post places with different rules.
