I’m a bit surprised by the lack of engagement with you after appeal, that alone would signify that the person behind the account is a genuine human and not a bot.
Can’t speak to .online but I know .Social is infamous for being a poorly modded instance (largely because they’re inundated with members). This obviously doesn’t make it okay and certainly doesn’t look good on their end.
One thing I would say, and I know this isn’t an issue users should be dealing with, but I’d highly recommend signing up to a smaller instance. Tighter community with (in theory) a more personal modding system in place.
Bold of you to assume its users want it to replace Twitter.
