It's (relatively) easy to prove who's shaving, we tested it with 2 big programs we were suspicious about and bingo! one of them shaved at about 25% an the other almost 50%, test ran in a week. We approached the program guys, one of them magically stopped the shaving machine (at least for the account in question) and the other simply terminated the test account. They promised 35 PS, but in fact they were paying little more than 17.50 . Anyway, for common people or people living out of the countries where these programs are based, sueing them is just a waste of time and money. Plus, you can prove it for yourself, but not sure if it's enough proof for a judge, prolly not (even when it could be "reasonable doubt")
And no, won't say which programs are those because we ocassionally work for them in other areas, so if you're curious, run your own test
