Better the devil you know. I dislike Paypal but there are few better alternatives.
Here's my experience with a new Paypal account and I'm sure the same rules apply to other providers.
It's a slow game.
The 3rd world country is a big problem with trust. If you can get an account, the "safety" algorithm will ping at the slightest provocation - temporarily locking up funds.
I live in a developed economy and I was still very careful. After 12-18 months Paypal trusted me and now they even want to lend me "Working Capital" at crazy interest rates.
This is what worked for me.
!. Consistent information: Your bank/ebay/paypal Address, Legal Name, Contact details ect - Need to be the same.
2. Increase sales slowly. High sales at the start or big jumps will trigger the algorithm.
3. NEVER withdraw all your money. Always leave 20-30%.
4. If you have problems, be EXTRA nice to call centre staff. Try the US number during US business hours and maybe you can get an American who is more helpful and open minded.
5. Give good customer service and be proactive. Sometimes it's better to refund and lose early instead of wasting your time. High dispute rates will cause you problems.
Now I have no problems and the rules don't really apply to me.
