How much is the three-piece set?

Recently, I've seen quite a few teachers teaching people how to create accounts. I took a look and wondered why they make it sound so simple. First of all, for something like fingerprints, you can find an agent on a certain site and use their link, which can yield a 20-30% return. Then, you just sell the three-piece set, but you don't teach people how to maintain the accounts. If you just jump into socializing, won't you have to change the accounts every half month? You also don't teach them how to set up a server or register an email, so how can they exploit the galaxy like this? Sigh, nowadays, teachers are really unbeatable just to sell the three-piece set. I even doubt whether you guys have ever exploited anything at all.
