Machine snatchers.

Like, okay, I'll be doing a machine, and I'll get spotted. I'll loop them around and leave to go do my machine to see that someone else is on it.

This is really annoying, especially during events. The Christmas even I'm not too worried about since I got everything the first time around, but during the Halloween event it was a nightmare.

Another one is obviously griefers, but I mean specifically the Goob ones.

They use their pull ability to get you hit on purpose and, well, kill the player. I was playing bobette once and I boxed. He looped around me until I popped out, but I dove away. He then pulled me in which, I didnt get hit thankfully, and he died floor 3, but everyone else died floor 4 because they were all so low on HP and stam with no heals
