Okay, I've got a bit of a grievance.
I understand people want to be cuddly and fun and affectionate in the fandom, but you need to learn your limits. If someone tells you they (or their character) don't like to be touched, please don't push it, especially if they are trying to be polite about it. For many people their characters represent who they are, and this verbal assault of "They need hugs" "I wanna yiff them" "They need my AHEM in their AHEEEEMMM" needs to stop.
If you wouldn't force a hug on someone in person, don't force one on them online either or their characters, show some respect, please, I'm getting very tired of having this conversation with people, especially when I try to be as polite as possible and have to say "no" various times.
Don't be a creep
Respect people's boundaries not just about them and their bodies but their CHARACTERS
Respect that not everyone role plays
Learn how to take a hint
Don't be a d-bag
There are better ways to get someone's attention/gain their friendship.
