The server has a votekick command you can try to get rid of nuisance players by typing "votekick" in general chat and selecting the user/reason from the popup list. If not, you can use the contact admin feature in-game or in a browser; type "contactadmin" in server chat or go to http://www.sourceop.com/contactadmin.php . And yes, they are many many SOP admins (8+) who play on that server and have admin abilities. If you know any admins or server regulars you may want to ask them as-well to get a hold of an admin.

As for your bad experience, unless you have names/screens/chatlog/demo or something for us to look into, I'm sorry, not much we can do about it now.
