It seems to depend on the browser. Trying to reach it with Firefox results in the server error you mentioned. But with Chrome it still loads halfway. I agree with you that it doesn't look good and I have no idea what is going on. I will go and check their ANN thread, the Scam Accusations, and Reputation boards to see if there are accusations against the site. If there are, I will immediately remove them from my threads. If not, I will give them some more time before they are definitely removed.
