Its a shoking news that Paypal ban account for cryptocurrency transactions. If they suspend or ban account related to suspected transaction, many verified members won't trust on Paypal for anymore and new members won't create account of Paypal for their bad practice after they declared 4 coin's acceptance.
They already do that before so I will not be surprised if they do it again, they are not supporters of crypto currency they are just using the popularity of crypto currency to earn from its users and nothing more.
I actually found article from 2014 when they are banning users from Bitcoin talk for selling goods related to Bitcoin or crypto currency.
