Like "condeleezas tit", "putins nutsac" and "Miriels flange", "Agent Proto" is a totally inappropriate name for Xbox Live, or so say Microsoft. I think they have Dan on a permanent watchlist or something.
Out of the four it is obviously the most vulgar. I am still annoyed they made me change condeleezas tit but Agent Proto, yeah pure filth. Probably warped the minds of all the 12 year olds we encountered on Halo during the 5 days they let me use it tbh
