So, ok, guys. I have this question if anybody knows. I wasn't planning to do any trades with them, this is simply for educational purposes.
Exploring paxful I've noticed there are lots (all of them, I think) demand (not even ask, but demand saying it is mandatory) a phone number in order to trade. Ok, many traders want that, not that suspicious, right? Well, the red flag is that tons if different accounts have these ads to buy or sell and they been copy/pasted.
it goes like this:
Please read carefully.
1. Initiate the trade ,
2. Paste your account details and valid phone number please (very necessary).
3. Alert me if am not online 08057708920, Whatsapp 08057708920. thanks
4, I will always give positive feedback. kindly do the same
5. A very big thanks and hope to trade with you my friendand the variations of that. Here is one example
https://paxful.com/en/offer/v6W1M7Vgxor but you can find tons more of those. Same trading rules even if payment method is Bitcoin Cash. That's a red flag for me. Now the question: why would they need my phone number? Obviously for some kind of scam, but what possibly could they do with it? Anyone knows? Really curious
