Paypal is really one of best and high trusted payment gateway service and if you call their customer support then you can clear all the issues instantly..before that you have to verify your account with all the required proof then only your limit will be left...
If your paypal account is got limited then there will be some violoation issues behind the action you had done..i used and still using paypal for my websites essaysmaster and topessayreviews i didn't face any issues yet..
The important thing to remember is, try to log in to your account from the same device, location and same IP. If you are travelling to anywhere and open your account from any other different country, it will get account limited issues. So, please be careful.
