Racism is allowed, it's part of freedom of expression.
Well, not really; otherwise hate crimes wouldn't be considered as such.
I guess you meant that it's allowed in the forum, and seeing how many sexist posts do still exist, and probably won't stop being created, it's safe to assume that the same will happen with racism or any other attack on minorities/oppressed groups.
It's dumb anyway on a forum, I couldn't care less about your color or race. There's no KYC, you can be any color you want online.
Yeah, lol. If it was a forum meant for a broader audience, I may disagree with that too, but knowing what a niche bitcoin/crypto actually are...
I, however, believe that if there's some systematic and constant on a certain user or group prepretated by the same individual, after recovering what should be considered "enough" evidence, some actions could be taken. I am of course talking about some extreme cases, and not about some random posts from time to time, which may also be problematic, but this is the internet, so kind of "get over it". And by extreme I mean a case in which it's actually disturbing the community in some way; luckily I can't think of any example here, as I don't recall seeing anything that'd fit happen.
Besides, if someone does feel the need to "report" those posts, they could always go to the police and report them. It won't have much future, but I know that stuff is actually doable, the same way tweets can get reported.
