Thanks for the link and for your concern Graffi.
The blessing of the spam curse is we have our own anti-spam measures that have been doing well so far. About a year ago we got buried with spam, however, I made a few changes, that seems to have been very successful. It's and ongoing struggle, and we'll put up the Captcha (blurred registration code) when we have to... however, that just invites the next battle to defeat the captcha.
I'm sure everyone will be on the lookout, and we'll add more restrictions as needed.
