[QUOTE=chalsall;435329]No real exploit. If someone wants to give you credits, is this a serious problem?

LaurV played a bit of a joke on me a couple of years ago. He gave me some serious credits.

Perhaps it's a problem if someone gives you bad results.

Yeah, I don't think it's an issue. Worst case, someone "joins" your account and submits a bunch of bad results, but any type of good/bad in terms of what kind of cat 0 or cat 1 work you get is based solely on that CPU, not the user id.

Yeah... weird huh?

Not my idea, Kracker did it to me first, giving me some DC credit. That is where I got the idea from. :blush:

edit: This has another funny story attached to it, after the joke ended, he switched his computers back, but forgot one of them, which still continued to report results on my name for few consecutive months, haha...

Only for clLucas, which is very seldom used.
cudaLucas has the shifts implemented years ago.
