Don't know that either, I was part of their signature campaign as was a lot of other reputed members and everyone was paid in full and I haven't seen any scam accusations against them. There was a little dispute when they were asked to provide their cold storage addresses, which iirc they refused to (don't know why ) and .. don't remember what happened after that but they closed the Sig campaign after a while and must've closed the site sometime after that.

Edit: This thread will explain what happened: https://bitcointalk.org/index.php?topic=1066980.0
