Bots taking up space in the chat rooms. What can I do about this?

My friends and I are regulars in a chat room, there didnt use to be many bots in there, but a couple weeks ago someone put about 20 bots in there and according to the computer they have been idle for about 14:47:14. They are taking up soo much space my freinds and I are having such a hard time to get in and chat. Is there anything I can do about this?
