I mean; some that I know of is to have well-known OCs and offer YCH commishes... (seen NSFW ones fly off the shelves, since it taps into the fanbase.... and can get insane on price with no AB, depending on demand...)

One friend of mine was doing tons of adopts, but those kinda settled down as of late...

Hmmmm... I mean, when all else fails, *Pr0n* lol

cloning.. offering a YCH or Adopt, but it is all the same drawing with minor colour or outfit changes. Just cut and paste to a new file and charge full price for each.

=^.,.^=

I hate when they do that!

indeed, very sleezy.

selling adoptables. Means you can sell the same character just color swapped multiple times, and for some reason, many people are fine with that. I saw artists really selling the exact same outlines that way like 5 times

This one is surprisingly common!

YCHs come to mind, tricky part is figuring out scenarios that'd be interesting enough to get takers
