when i had an imageboard i set almost all unicode emoji as an automatic permanent ip range ban and it set a cookie to autoban another range if the offender tried to circumvent it, all those that could circumvent it were not chased further because they prove they were not raised as phonefags with no knowledge of basic mechanisms

western sideways emotes were fine and so were vertical nip emotes
but the lazy and obnoxious unicode emojis were a death sentence
i hate it that almost everything turns my emotes into emojis when i want to send a :P or B)
