I love MTF, and this is one of my only complaints:
Random audio blasting out of my speaker drives me crazy, especially if I'm listening to music loudly. The little guy in the smilie ad who yells "Helloooooo" makes me want to gouge my ears out. If it continues I fear for the future of my hearing.
I would never buy from such an annoying advertiser. I wouldn't even click on it.
Obviously, one solution is to sign up for premium membership. But let's say I'm A) poor, B) cheap, or C) from Colombia. That option becomes difficult.
Those who are just discovering the site might be encouraged to stay away if they keep hearing these ads.
Perhaps you have no control over whether ads have audio or not, but if you do, thanks for listening.
