They feel free to take any credits you've accumulated and are arrogant, uncaring and unprofessional if you try to communicate with them. They want you to refer people to their site, but if you refer a lot of people (as I did), they will flag your account and steal your credits. They don't take responsibility and don't care if you've been a long standing good member. If you have any credits with this site or their sister sites SwapaCD or PaperbackSwap, you should use your credits as soon as possible, while you still have them, and get out before they rob you!
