Can't flag Polls

Some prick is spamming the Steam forums with threads about free American Football or some shit. It appears you can't flag his posts thought. Is it because he has them all as polls? The flag option is appearing everywhere else, but when I hover over his posts I get nothing. Might be useful to get this fixed if it is a problem and i'm just not missing something.

Not a glitch. They said the new site would have polls you could flag but I guess they decided against it for some reason.

PM the mods about it (you know about that link, right? It's over there ---> under Contact the moderators).

I guess you could also flag the first reply (if there is one).
