Most of them evolve the same way:
1) Seller launches WSO
2) Review copies are given out
3) Reviews are left by people who received free copy or by acquaintances
4) People buy WSO
5) Buyers reviews start coming in
6) WSO provides what is advertised or turns out to be a flop
Personally i place zero stock in "review copy" or "friend" reviews, but some people do.
Here's my question:
Should people who leave glowing reviews for a WSO that turns out to be a total sham be held accountable?
