Not absolutely everything that could feasibly be considered trolling is listed in the One Stop Rules Shop; players are expected to show a degree of judgement as to what is and isn't acceptable on the site. The "Autistic Screeching" meme has long been regarded as offensive here, and whilst it's true that we try to judge a player's intent when warning for trolling, that doesn't mean that you can get away with posting things deemed offensive simply by arguing that you didn't intend to offend anyone, or were ignorant of how your post could be construed as offensive. Obviously we can't know a person's intent with any degree of certainty, and neither can we judge with any degree of certainty whether or not poster is aware of the meaning or context of what they're posting. It's up to you to judge whether what you are posting may not be permitted by the site rules. In this situation, you've clearly misjudged.
I'm sorry, but given there's a clear precedent for warning people for the "Autistic Screeching" meme I'm going to uphold Ransium's warning in this case. Appeal denied.
My question is obviously why is it regarded as trolling? It isn't mentioned in the rules at all. Apparently it is regarded as offensive? To whom exactly? Literally fecking no one. Furthermore, something being "offensive" is a very loose standard to apply when prohibiting something. Anything can reasonably be considered offensive. The terms "gun grabber" and "gun stroker" can easily be considered offensive, yet aren't prohibited (those were the first examples that came to mind).
I only raise this question because moderation seems to have only recently begun punishing players for it, despite the fact that OT says it has long been considered offensive and the meme has existed for an eternity. And given that it isn't listed anywhere in the rules, it seems decidedly unfair to warn and ban people for it considering that they wouldn't have any sort of way to know the moderation team regards it as trolling, and never takes context into consideration when ruling on it at all.
