Well I just started and I'm having fun. I just tend to ignore those types of people or anyone weird and annoying. Like yesterday, here's a funny story, I was walking around the dojo? I think that's what it's called. You know when you start out you have to fight some people then it sends you to a house, and then you go back out and talk to the instructor guy. So I was there and I learned how to lean against the the railings or whatever they're called, and a random guy came over and gave me a toast or "cheers". It was funny. xD And then a few seconds later another guy came over and leaned where I was and said "cute couple". lol. So I ran away.
I remembered that I had to talk to the instructor guy so I went back and the same guy found me and said that the instructor guy was my bf.
And then I left to do the mission, which I failed, and then I went to the house and exited the game.
I wouldn't call that abuse just weird people. Maybe it was just bad timing on your part and there were bullies there. I haven't met anyone mean yet.
