I really don't know if she pulling in a fat amount of money past the sub price, if you buy any of her ppv I don't think you really want more because of how bad they are for what you pay. She makes exceptionally vanilla content with a rare chance of her uploading a ppv with some sort of anal content to it.
Onlyfans is ultra competitive but outside of being a 10 she really doesn't bring much worth paying $60+ a ppv. Her JOI's are next level bad though. Oh Liz just put the effort in
