Basically we've switched to a backup to fix the problem. The dodgy script is going to be pretty well burried into the site so I think we'll just have to live with 3 days of lost posts On the bright side the patches and general re-works of the site scripts should stop this from happening again (although in hacking nothing is impossible).
This means that Any bets made or sweeps selected may have been lost so if you play those games check that your post is either gone or before the backup date.
It would appear the site was briefly compromised by someone with malevolent intentions, and they succeeded in inserting some kind of malicious code into the site, which would probably have tried to install something nasty on users computers. Google highlighted the site as having been attacked, and the Chrome browser blocked access to not606 for a couple of days. Since the attack, Mick (site owner) has removed the inserted code, and has got someone plugging the holes in the sites code. How vBulletin (software provider) left such holes I don't know, but Mick is sure that no user data (usernames, passwords, emails,etc) was leaked, and that this shouldn't happen again. As part of fixing the problem, Mick had to revert to an older version of the sites database, so 2 days worth of posts disappeared.
Ah. Thanks, DHC. Obviously I was away at just the right time! As to the "two days worth of posts"; based on what I've read, it seems to have been quite auspicious; perhaps calming and karmic both at once! P.S. I'm slightly concerned at your mention "holes in the site's code" and also of personal details; but from what you say, I can only trust that all now appears to be in hand.
As far as we're aware, no data went missing, the 'hacker' appears to have gained nothing from it, mainly thanks to Google flagging the site so quickly. It's good internet practice though to have a different password on sites like this to your email one, so presuming that's the case, even if we were hacked, your emails would still be completely secure.
