Stand, absolutely concur, I actually told Chris that using those tags would likely get him banned/kicked by an Admin.
Since then Chris sent me a few messages via Steam Chat, he was obviously remorsful and upset about being banned from the public server and I suggested that he put a post up in the Banned section of the website to apologise, which I see he has done. We also had a good talk about who can use the MAG tags and more importantly who can't !!
