Right, because they couldn't possibly have stolen it from him---or even gotten it from the same designer. Designers have been known to relicense works if they were generic instead of branded. And that is not branded. Try contacting the project's webmaster and asking before jumping to conclusions, Matt.

That said, Khile, there is a good bit of risk for having a lookalike forum. You should check with your designer and make certain that it is a lookalike and not a rip. Stress that he has to have created all the graphics himself, or have used them with permission. I'd point to that package too, to make him sweat and hopefully be honest--if he was deceitful in the first place. If it is merely a lookalike, I'd make a forum post here and there announcing this and quoting your designer for safety.
