Bollocks, quite frankly, for a couple of reasons.
Firstly, if he had made £100,000 in a such a short time why would he willingly give it all back in refunds?
Secondly, I clicked on his profile a couple of times. His highest liked post had 3 likes. If your engagement with 5,000 people who have willingly given you £20 to see pics they could find on Instagram or less explicit than you can find by googling him is 0.06%, you’re clearly doing something wrong.
His Twitter account only has 71 followers too.
