As mentioned, how the hell do you KNOW that there's different rules for Leavers and different rules for Remainers?
Because I could plainly see the posts that were deleted and the posts that were left. Including, on one memorable occasion, one post by a remainer which a leaver had quoted in its entirety so it could still in fact be seen (even though the original post had been deleted) and was plainly not abusive and did not infringe the talk guidelines in any way.
1 - how do you know how everyone voted? You don't.
Because all of this took place on the Brexit discussion board between posters who were all openly on one side or the other. Obviously. 
2 - have you asked each and every one of the posters if they've had a lock out of their account? Or did you just ask inside of your echo chamber?
None of the prolific leavers mysteriously disappeared, or started posting under a different name and complained that they had been locked out of their account. Several remainers did, and were met with gleeful cries of "well you obviously deserved it, hahahaha!" from goady fuckers leavers who had actually and repeatedly been abusive towards remainers without suffering any consequences.
I did explain the banning. Aliens or gremlins. Well,it makes as much sense as the theory that and I quote "MN HQ is on it too!"
No it doesn't. HTH.
