Well, he might have... Is the board and its threads visible to non-members? IIRC it is... And even if it's not and he's signed up as "filip" on the boards (because I've seen that name on the members' list), then this member hasn't logged in for ages, but if I were him and signed up with my real name, I'd also get a substitute account with some irrelevant username to roam around in the forum hidden!
But then again he might not be that foxy... After all, he's been living in Sweden, among Swedes... It wouldn't be safe to judge Swedes with Greek criteria and according to Greek standards! ;D
