Well I am trying to find it on OLMSS web site, but there official facebook page of blacksheep and OLMSS has the same thing posted.
In 2012 I went to OP Blackseep at Ft Drum Mout facility. They were caught on helmet cams blatenly cheating not following rules, hit calling Force Recon attended this game aswell and they can verify. After that game blacksheep announced that they were banned for one year from his games. What i posted above happened over the week end at OP Lion Claws. I have found the official post from there web site.
hope this helps
