Alright, it seems we need to cover some ground today.
1) Nobody here has immunity from the mods.
2) Calling other posters trolls publicly, whether the title is "earned" or not, is a clear violation of site rules. You all know better, and the hypocrisy of calling out someone else that you believe to be breaking a site rule while doing that very same thing yourself shouldn't be lost on any of you, either.
3) There is sometimes a fine line between trolling and teasing (or otherwise displaying an "edgy" sense of humor). One is generally intended to be destructive or nasty (trolling) to the community/person it is directed at, and one generally isn't, even if it can be provocative at times. Going to another team's board to make fun of their team and shove your team's success in their face is classic trolling. You don't belong to the community that you are trolling, and you are intentionally acting in a destructive and nasty way towards that community. Playing a prank within your own community is generally not interpreted the same way, as one's goal is generally not to poison the community to which you belong and actively contribute to. The burden of proof standard is higher, with the benefit of the doubt being given more often than not. The goal is to prevent intentional toxicity, not to make this a "no fun zone" where anything even remotely edgy or controversial is not allowed.
People will sometimes have different interpretations of the same event, even among moderators. Heaven knows my wife and I have different interpretations often enough when I tease her. It's a shades of gray area, and we do our best to manage this community in a way that maintains some semblance of order without stifling the voices and personalities of those who participate in these conversations...which is one reason why I'm attempting to use this as a teaching moment instead of just purging the conversation and infracting a handful of posters who are clearly invested in this community.
Bottom line: It's not on you as users to dictate what is considered trolling and what isn't, and it certainly isn't your place to pass public judgment on another user. If you have questions or concerns about someone's behavior, report the content in question or send a PM to a moderator. If we have to go through this again, I'm going to skip the explanation phase and move right into the purge/infract stage.
