Quote from traderchi128:
He is the scummiest of the scum. He sells a bullshit strategy (good luck getting locates on the crap stocks he tries to short) to young wannabe traders who have a few thousand dollars in their account. He basically leads these sheep to the slaughterhouse(between high costs of trying to trade these stocks, and the fact that the only trades most of these new guys will get done will lose money....anyone who tries his trades are doomed).

Very common. I'd bet there's more money in the brokerage side of it than in selling signals. Referrals for new accounts and % of commissions. Probably without any government oversight or having to register NFA, RIA, etc. If the edge were that strong or scalable, he'd keep it for himself or start a fund.
And if you just want to play the microcap space, there are plenty of competent bloggers who cover it for free.
