In my research setting up my website shop I found many examples of paypal doing this when people use the word "mod". I went through and made sure my site doesn't use the word mod at all and instead I use the word "upgraded". I also recently removed all the consoles that have "upgrades" from my store and will only sell them on facebook marketplace. Even just repaired WiiU's with a larger nand. With the introduction of non-human moderation tools these kinds of bans are just going to become more and more common. This was probably a targeted attack, as you suggested, but mostly the enforcement has been automated and the people you talk with at Paypal aren't smart enough nor powerful enough to over turn what the automated system decided. It's tough to be someone who wants to fix, repair, "upgrade", and just be a part of this community in any meaningful way now. Especially for someone just trying to break into it like me. No matter how skilled we become at installing, diagnosing, repairing, etc... Figuring out how to not get in trouble for doing so is really difficult and complicated. Maybe you can use something like Venmo or cashapp to collect payments. Maybe a business partner who can setup and take payments under a new LLC. There's options to move forward, you just need to figure out which one you want to do.
