This claim still needs some development, but the OP of that thread would be able/allowed to open a type 1 flag against GP.
With sufficient support, it would give GP the "!!!" tag next to his trust score, and show a red notice (instead of neutral yellow) above his threads.
You are wrong, as type 1 flag would not give GP this tag "
!!!" you are talking about. GP already has 2 active type 1 flags on his profile.
Hah.
Thanks for rectifying my post.

I thought type 1 flags were the ones for the breach of agreement, and the type 3 the ones based off forum users opinions.
Mistaken both, but anyway, OP of that other thread can give him the type 3 flag. Based off elements I'll support that as well.
