It's not your isp, someone's hacked the forum. I saw a bunch of that crap today too and there was 2 hours, right when this shit was showing up, that the forum was dead slow. I saw maybe 4 or 5 examples of those hacks.
It's a sort of dns spoofing (the purebasic.fr didn't redirected to our server for a short period of time), nothing has been compromised. I have mailed the tech support to gather more infos about it and i will let you know when i got an answer.
Thanks Fred, I'm glad it's all ok. I hope the people who did this (if they did this intentionally) will pay the price of doing this... I was thinking at this matter from your perspective, I mean I would be very sorry and mad if someone would start stealing stuff from the registred users area.
