That's why i don't pay attention to Twitter. Only the Chans of the world are worse than Twitter.
You can find less toxic people on YT comments nowadays.
I don't even know why a creator would waste his time creating a Twitter account to engage with fans.
You not going to find people like that on conventions, at least not in the vast majority, because people in real life don't behave like they behave on Twitter.
People on conventions are looking for a good time and they are mostly respecfull to the creators.
