Goodrum is actually very clever - one of the greatest internets trolls ever. He's got most people fooled, but not all of us. It should be obvious from paying attention and reading his posts carefully that he's fucking with us all.
Getting up on stage in a thong looking the way he does in order to shock people for his own amusement is but one example - although I would guess he probably needed to get quite drunk to be able to do so, at least the first time he did it. He and his buddies probably still laugh themselves silly over his "contests", his "confrontations" with DA and Billy, and his "excuses" for looking the way he did onstage such as "mis-timing his carb-up due to oversleeping", etc.
My guess is that he's also faking the homosexuality, the trailer and other low-end dwellings (probably some of his rental properties), and the laughable "businesses" he talks about on here. Of course those "businesses" could be very real fronts for much more profitable activities that may not be so legit in the eyes of Big Brother.
