It says that on just about EVERY stock PCS is promoting. Don 't think for a second that this is done outside of the company sphere of influence.
If a company WANTS a promotion, it will get one from PCS and it will say "Compensated by a Third Party."
It DOES NOT mean that the company had nothing to do with it. it means the legal transaction occurring that constitutes the compensation was not done DIRECTLY via a company transfer method.
Don't be ridiculous by falling for the "Third PArty" junk. The company CHOSE to be promoted by PCS.
