Even before AI I remember reading that many of the "custom designed" logos on Fiverr were just ripoffs of existing trademarks.

There are sites where you can buy 200 different shape stencils for $100, and most logos are just those with text added.

When I found out years down the track that I paid like $1000 for a “premium experience” to be offered 6 or so stencils like this, I was pretty furious. Luckily, I picked none of them, and made the artist draw it exactly as I later described.
