Unlikely its an exit scam unless it was the forums decision to remove the posts. There would be no reason for Ozpharm to ask for the posts to be removed if exit scamming. They would want the posts up as long as possible to get as many orders as possible, then after a few weeks when people start complaining about not getting their gear they would make a post apologizing for delays and assure everyone that things are all good and they would get even more orders. They had an excellent rep on this forum, I cant remember ever seeing a post that was negative towards them except one where the guy thought his oil was underdosed but had no proof except for how he felt.
More likely theyve got a bit of unwanted attention and its a pretty risky business to be in. Youve got to remember that in Australia anabolics are classed in the same law category as heroin and other hard drugs and you sure as hell dont see those being sold openly on the clearnet.
Fingers crossed for OPL that things work out.
