All social networking accounts are public unless their users make them private, therefore any information available online is viewable to anyone who happens to be interested.
Why would people be interested in someone called @moetandmuffins on Twitter? Perhaps because she/he has a fairly unusual nickname which happens to coincide with someone else who uses the same nickname on this forum even if it's not the same person, and 'moetandmuffins' on this forum seems determined to defend Mike Mason in particular despite lots of on-screen evidence to the contrary. Revealing the identity of 'moetandmuffins' (Mike, his partner, Ryan or someone else) is key to determining how close to Mike and/or the Sit-up channels they really are, whether it's an obsessive fan or someone who's close to Mike personally and/or works for the Sit-up channels.
This, believe it or not, is important to know if we're to treat their opinions seriously given that there seems to be very few people prepared to stick up for Mike Mason for whatever reason(s). Would you really believe an online review of a hotel written by the wife of the hotel's owner?
My opinion? Mike Mason isn't technically the worst of the liars on these channels and is apparently cleaning up his act as well, but his past behaviour has been somewhat ludicrous to say the least.
