What I'm about to talk about is a serious issue.
I had shared some art of a character of mine in a discord server when this one person, later 2, started talking about doing some not great things to him. I was very uncomfortable with this conversation and said "no" and "stop" a few/several times but they didn't. So i left the server, i wasn't really active there anyways.
Please don't ever do this to someone, it can seriously effect someone's mental state/mood. I know i personally am rather upset and ended up cutting my drawing session short because i just wasn't really in the mood anymore, not if people where going to say/threaten that kind of stuff.
A bit after i left a friend who was also in that server shared a screen shot showing how those 2 where surprised i left and saying how it was "just a joke".
It isn't "just a joke" if it makes people genuinely uncomfortable and upset, it's not funny and causes people to feel not great.
If someone says that theu don't feel comfortable, stop, don't continue, or say "but it's just a joke" because that's a jerky thing to do
