Actually yeah they do prevent you from being there sometimes. There is one person in particular on Atlantic who sits down there literally all day some days, and whenever she sees another person she will intentionally drop rocks on them trying to kill them, harass them, try to get them killed various other ways including with exploits, and if the person still doesn't leave she will even go get Greater Dragons with multiple accounts and start releasing them down there just so they will attack the other player. I had to boot her from my guild 2 years ago for it, because I was getting such a huge amount of complaints about her behavior from many other players. When I asked her about it she pretty much said she does it to sell tangles for real money, and screw everyone else, she has no plans of stopping.
Having another player trying to get you killed non-stop makes it rather difficult to both fight the boss and avoid their harassment tactics. Having 5 of her released Greater Dragons attacking you at the same time doesn't help either.
