Firstly, HelloClan doesn't play COD 4 anymore so this does not mean much to us in a clan sense and secondly Foxeywing doesn't play COD 4 with this clan.
That is without mentioning that the "evidence" is far from concrete when all you need is an image editing program to add some red squares. Foxeywing having an account on a website that supplies hacks doesn't mean much either, especially when his join date and last visit date are identical, as most hacks get stopped and a new one is required. His profile doesn't even say he downloaded any. I'm sure a lot of people have accounts on websites that are somewhat shady, but it doesn't mean we partake in any of its services.
If you want something to come of this, you might be better off informing those that it matters to, instead of a clan that doesn't play the game; even more so when the person you accuse isn't even in the clan for that game.
