As was previously mentioned up there, and repeatedly all over the forum for years now: Watch what you share. Some of the things you've promoted are generally bad ideas. You aren't warning the new kids about the real risks involved in some of these suggestions. Hustling leads through classifieds is older than this forum, and has been played out for awhile now. Sure, you'll get some conversions, and then you'll get caught. You'll either lose your commissions, your accounts, get sued, arrested and fined, or all of the above. The same goes for your other suggestion of scraping emails and blasting like crazy. Bending the rules is one thing, breaking them and putting yourself in legal jeopardy for a few bucks is an entirely different thing. Get your money how you get it, but don't throw suggestions out there that convey massive risk and pretend like it's all good. You're new here yourself, so you haven't seen what happens when shit gets real.
Blackhat is about being smart, not careless. Carelessly breaking rules, or laws in these examples, carries heavy consequences. Always remember: If you're receiving money from an activity, you aren't anonymous.
