Again, thank you for reiterating my point that this is NOT the behavior of a private source. This is the behavior of a source that wants to pick and choose it's buyers... Most of the time these sources are repped by 1 member on a board, who receives compensation for this "filtering" of sorts.
Rep PMs members about a good source
Member buys AAS
Member is encouraged to publicly reveal positive tests
Member is contacted by other viewing members
Inquisitive members are sent to the source for filtering, generally the referring member receives a discount or free kick backs.
The monster continues to grow
A few bad bloods show up, member goes to source first, is discouraged from showing negative results, possibly threatened by source who has their identity
All other members continue to buy bunk gear
That's how this shit works.
