i was thinking of integrating pp button to my website to make things easier on me and my customers. I sell high risk items. I don't like the fact that the button would link my site to pp and they will close my acct down.
If you're not selling high risk items, you shouldn't have problem
if your paypal accounts gets limited, you cannot add a new paaypal to your website anymore or it will gets limited too.
It takes more time to use paypal invoice, but it keeps your account safe, also you can use several paypal accounts for the same shop to spread the incomes and not loose too much money if one of them gets limited
