A tip to avoid Paypal banning you, NEVER send or accept Paypal as friends and family when selling or buying BTC. Take the hit on the fees and avoid suspicion. Paypal will flag you and it will most likely result in your account being banned when they look into it as was done to mine.
What reason did they say exactly was the reason?How would they know what the paypal was used for if nothing was put in the notes from the sender?
How many family and friends payments did you take? That might be a proper reason for them to flag if too many were sent that way to and from numerous paypal addresses.
It happens to ptc sites all the time with too many sends and not paying the fees.
The first ban reason was "We recently noticed a pattern of account activity that, in our experience,
is usually high risk."
The transactions they wanted more info on was 2 gift payments I received and 3 payments I sent to places like ebay and steam.
My paypal email was admin(@)cryptodatabase.net and when several gift payments came in short succession it threw some kind of flag and they assumed it was for BTC.
When they banned me I told them they were gifts from some work done and they said next time to have it sent as payment for goods and services or they will ban me again for avoiding fees.
I got that taken care of by a phone call but then they turned around after they unbanned me and said I had another account that was negative and said I had to pay them the balance due to have my account unbanned. Needless to say I'm not paying something I don't owe so I'll never use paypal again. I tried to tell them I only have one paypal account and it is the one thats 4 years old but their customer service is shit and I shall not be blackmailed into paying them to gain access back to my account.
Second ban reason was, "Please resolve your negative account
