Glad to finally hear some kind of confirmation of a compromse on that other (locked) thread. I think the reason that not many people have reported spam as a result of that attack is because most people don't use site-specific email addresses, and the spam being sent is conspiracy gun-nut stuff, not about basses, so if they received the spam most people wouldn't know that it was anything to do with basschat. Also, it's quite possible that they only took some of the database, and that some people's ISPs are better at filtering spam than others. But the fact that more than one person with a site-specific email address for basschat reported the spam means that it's most likely it came from a basschat-compromised database, even if others didn't get it.
For interest, I changed the email address registered on the basschat site on 2 Jan, and that new email address hasn't received spam yet. The old email address has still received some, e.g. the Diana one the other day. The fact that the new address hasn't received spam is a good sign, as it probably means that the database hasn't been compromised since 2 Jan.
