By trolling nonagressively I simply mean not being genuine in arguments, and playing along for laughs. As long as none of the conversation turns harmful or rude it should be fine right? :|It's still against rules and when it stops being entertaining for anyone but the person or a gang who is in it just for personal lulz it becomes problematic for the forum atmosphere and cannot be allowed to go on.
It's not like such arguments and bashing are limited to what's canon and what's isn't. The ones who like the series or want to discuss it should be able to continu, while those who come in only to troll are the ones being the problem and working against the idea of forum by discouraging the ones who want to.
As far as ppl causing problems, you being a mod would know far better about which groups are being troublesome and what for so it's not like I can offer any rebuttal along those lines
Especially since I am more of an outlier
