Paypal is evil and not going to hide how I feel about them, they have been on the dark side on & off since 2003, I was with them from the beginning of them! But anyway I have alot of history with this. Lately, it was what I call "the goldylocks years" of 2008-2016 when hardly anyone was closed. Since 2016 ... its apocalypse years (haha). Good thing crypto is here.
But.. ahhh here is no way to avoid it as it has spread everywhere, in every arena now and I guess really hitting ebay people hard too. Its now even into accepting commissions from sites. I know of two sites that some would would recognize if I said the names of them. AND it is not the site owners fault (I think they are being watched for awhile before closure)
Sorry to say but there is no certain thing to do as I had an account that apparently only 15% had, and did nothing new to cause closure, which got nabbed at the beginning of december - and two new ones in January. And I give up for awhile now.
I guess its luck or borrowed time now for the rest. Best thing for you and everyone else is to just dont depend on them, they cant be trusted - obviously.
