C'mon leave the guy alone. At least he's being cautionary. Even if this is "blackhatworld" that doesn't mean breaking the law is ok. What most on this forum fail to realize is thatin the USA at least, any deceptive tactic that is meant to intentionally deceive another party (i.e. cloaking, masking/hiding traffic sources, etc) in an attempt to gain financially is fraud. Because this fraud likely occurs over electronic means of communication (i.e. email, website, electronic payments, etc) that qualifies it as wire fraud. Which is a felony.
Now, sure, most often no one is "big" enough for any network etc to prosecute and most often they ban accounts way before it gets out of hand....but, again, that doesn't mean its not "illegal." Most assume that breaking the "TOS" is a civil issue. Which it is. BUT, it can also be a criminal issue if there was intent to deceive and financially gain. The "deception" part makes it fraud.
P.S. I'm not a lawyer but I've spent enough time in law firms with our business lawyers to gain a very clear understanding of the landscape. Be safe. Stay legal.
P.P.S. Don't flame me too bad. I'm not here to judge, just to educate. To each their own.
