This individual has now been thoroughly banned. Sorry it took so long, but we had to do some backend tinkering to make this work properly. A specialized team of thugs has also been sent to his house. We tried to implement breaking knuckles over TCP/IP, but our experiments weren't promising.

Anyone who's been scammed by this guy, please contact Support. For our convenience, please set the title to "Forum scam" and attach a screenshot of the PM you got from him. Also, copy-paste the code you lost, as well as his username, into the support ticket (so we don't have to figure out what kind of character-switching he has done). We'll give all those affected a code worth up to $14.99, to make things right.

We will also do some changes to the PM page to make it easier to spot a potential scammer.

TIL: they put odd things in porridge in Brazil. :P

Just a follow-up here. We are currently banning all of his accounts, but if anyone of you has a list of known scam accounts (ideally along with the original usernames they were impersonating), do let me know. In case we missed any.

We have personally decided that being forced to listen to an endless loop of "Friday, November the ninth, 2012. This week on GOG: in case you missed it, here's what's new!"is actually a war crime and punishable in the Hague.

This realization came from the fact that our video ninja is more or less forced to do this every week. Poor bastard.

I think this would be pretty extreme, and, at the end of the day, even that would be exploitable.

Our primary concern is helping people realize someone's trying to scam them. Currently the PM page doesn't offer much help to legitimate users.

We will make the account's rep and creation date visible in the PM site. I know it won't be this week - most likely our web devs will be able to implement this early next week. Not making any promises here, though.
If people still get scammed afterwards, we might start highlighting the rep and date if they're "suspiciously" low (like below 5 rep and 7 days).
If people still get scammed, we might put some kind of warning, like many chat interfaces warn you not to give anyone your password etc.
At this point, if people still let themselves get scammed (and I can think of no better way to describe such a situation), I'm not sure what else we could do to help avoid it, that wouldn't make the lives of new, legitimate users, more difficult.

Blood samples. Submit by mail, wait two weeks, and then your account is set up. I'm the head of marketing. I have the power to make this happen!

Bwaha. Bwahahaha. Bwahahahahahahaha!

After cooking for 6 hours, I could stand for an age of self-baking cakes. Oy.

Yeah, I just banned that account. Unfortunately with today's technology there's only so much we can do to keep someone out... The rep/creation date update should be ready within days, so at least there should be an early warning system in place for you guys.

Rep and join date are hereby visible on the Messages page. :)
