I'd say it's a loophole.
His post is on topic because he gives his opinion to the @OP's post and it's constructive as long as his post has a weight, right?
I sort of agree with you but not no the constructive part one as he is commenting on something already proven false.
You can send a message to the manager but let him decide based on his criteria and not your criteria
Of course, Hhampuz will have his own criteria and I am not the one to tell him what he has to pay or not. Besides, if it's only once, I might give him a pass. As I think I will do, because I said I would send him the PM because I was angry to see that he hasn't even read the first page, but if I find more cases like that I will do it.
