From my perspective, the point of observing that some bodybuilders have actively sought sponsors (and found them) is not to out them, rather it is to underscore that this activity is going all around fans of the sport. It is one thing for someone like Arvilla to say he didn’t know it was happening and quite another for others to deny it is happening or insist that it is a “rare” occurrence. As gordiano said
They continue with this pretense even when there are weblinks showing that so & so is or has been available for rent.
Review his threads; BEEFYHEAVYWEIGHT has provided you with plenty of names to sate your appetite. If you want more, you can do the research yourself. Again, I am not in the outing business.
By the way, I don’t mind people attacking me. Unlike some people here, I’m very good at ignoring threads, posts, and people that do not interest me. I do however find it amusing that—no matter the forum--guys like suckmymuscle and drkaje consistently show up in the gay threads that they ostensibly find so objectionable, even to the point of visiting and posting in the threads more often than I do. 
No need to get defensive. Pointing out the obvious (you rarely post non gay stuff) isn't an attack, merely the truth. Anyone else would have pointed out some of their posts unrelated to homosexuality but since you can't it's easier to pretend you're being attacked. It's laughable that you'd try pulling undergrad debate tactics and not expect to be called out. I've made similar observations in the past and you couldn't respond articulate a response then, no good response now isn't a surprise at all.
I'm sure you'll have something 'clever' to say like "ignore my posts because they're all gay" or "You must be gay for reading gay posts" or probably something about my wanting to do G4P, LOL! We'll certainly all think you're really, really.... really smart and be impressed so don't bother unless there's actually a real answer why you can't post or add anything to GetBig that isn't related to homosexuality.
No answer would be better than the same old "I'm rubber and you're glue", LOL!
