As far as I know, there have even been people who have been dinged for “copyrighted images” when they tried to re-use images of their own that they’d used before … so there must be some kind of check in place.
But I’ve been copied countless times, worst of it, my bio, I really hated that. I mostly gave up even looking long ago, though, people who do that, often also have gig multiples, multiple accounts, fake accounts, the works, no qualms about just doing it on another account when they got told off on one, or even again on the same account. Perhaps it’s worth the effort now, though, since the introduction of phone and ID verification.
I read that Fiverr put writing Fiverr gigs for others on the list of “do not’s”, but I never asked support about it, so I don’t know for sure. Just saying, in case you want to check.
