Have you seen lately some advertisements on Facebook calling you to come and learn this and that free
That's the new scamming technique.
They go to Google, download some knowledge which they themselves know just a little of. They then bring that to Facebook, ask you to come and learn this and that only free. ( I don't think even the most honest Nigerian these day would send one how to make money when he himself could go do and make Al the money for himself). After giving out the few stuffs they downloaded, they then asks you to pay some amount for master class. They make you pay such a small amount that one would readily part with. ₦1,000 to ₦2,000. You would think after all it's just ₦1,000 but imagine that from 50 gullible people.
The worst of it is that even non Nigerians partake. I've had to chatt with some from Ghana, Gambia, Cameroun, Zambia and South Africa. Now non of these would want to have anything to do with Nigerians.
While most of them are scammers, some very minutely few of them are sincere but for circumstances.
Imagine one who paid over ₦100,000 to acquire a particular knowledge, ( Some even pay over ₦1m), come online to teach and get back his money. In few days he's able to get about 500 students into a group. And after teaching some little, he tells them to pay ₦2,000 for complete study. Then you just start seeing from the group "this exists the group, that exits the group" till just about 5 people (only) were able to pay. The sincere guy could not possibly give out that valuable knowledge for just ₦₦10,000. That's when you start seeing films in different colors.

To keep yourself from all these people, follow these steps;

1. Find out where her she acquired the knowledge and when.

2. Find out from Truecaller, the numbers he gave out. If new number without information, then he's a scammer.

3. Visit his site. New sites or sites on the makings; are scammers.

4. Visit Youtube to see what stuffs he's been dishing out. If non, then he's a scammer.

5. Search for his name on Facebook. If there's no much information as to what he's been doing with he's suppose knowledge.

6. Request to meet him in his office. ( One once told me he got over 300 students but he's about taking an office).

7. If he tells you a final date, them he's could be a scammer.

8. Never visit the site nor click hyperlinks from them untill you are able to trust them.
