https://sanctioned-suicide.net/threads/profile-picture-guidelines.82591/ I can see where you're coming from. I think 'we' have established that while many users don't agree, the site mods and admins don't have a solid stance on the matter, or any enforceable rules against it.
Concerning potential (or likely) trolls, the difficult thing is, we as sincere users are here on honest terms, with good intentions. We put effort into our posts, contribute a part of our identity in doing so, and the dialogue we engage in is meaningful to us. We feel the need to share and stand up for what we believe, try to make constructive contributions, grow with our little online community, and inevitably we invest a lot in doing that. When something bad happens or there is some trespass, we feel the urge to apply our efforts and become personally involved.
Trolls on the other hand are simply here to fuck with things for their own agenda, which could be as simple as cheap entertainment. They aren't emotionally invested in being here, they can effortlessly integrate with the forum and stick around by simply not being too obvious. Like some sort of psychological jerk-judo, they can observe what makes people tick and use a minimal amount of effort to illicit a huge response- all the while remaining completely detached from the repercussions. Create a little discord here, sow a little chaos there. Sometimes they even have groups that work in cahoots. A lot of them are more tech savvy than the average member and might operate multiple accounts. It's almost like a job, just showbusiness, nothing personal.
I think that unless people don't care or are quite gullible, they can usually tell the difference between trolls or those just using a dummy account for some hidden agenda, and someone who is genuinely sincere. If not, then I guess they will be troll snacks. It's the nature of the internet, after all.
I personally think that the number of fake profiles, straight up trolls, throwaway/dummy accounts, or social engineering profiles who are simply tallying up bias likes and support or generating certain content in order to sway public opinion in some way, probably exceeds the number of genuine members who are here posting as... their true self.
My solution is to not get too emotionally invested if possible, and if the mood is right, strike a fair blow to an antagonist when I see the opportunity. I'm not overly concerned with popularity here.
