[Can't do quest because of Boosters]

Hi,

I have a character on Extreme x5000 server, and need to do a quest in Aida (Kill 10 Hell Maines).

Every time I go there (1 week+) There are 4 characters (clearly from the same person...) 24/7. 
I can not kill them, and cannot catch the Hell Maine before they kill it. Is there something that can be done in this situation by admin maybe? 

Thank You.

Thank you. I was not aware I can withdraw them. That helps a lot ?

Hi, I have 100 Bon. Web, but I am not aware of any features that require Web Bon. Is there something I can do with them?

Thank you.
