An excellent solution to stimulate sales would be not to introduce any subscriptions to devalue the work of artists, but to remove all AI content so that the buyer can normally search for the right content on the site without wasting time flipping through pages with low-quality AI content, which many buyers ignore.
Normal site content, filling with high-quality content would definitely stimulate sales, there is no need to spend a lot of money on storing garbage AI content that does not sell, but only clogs the search and pushes users away from the site.
It would also be appropriate to introduce moderation for the uploaded content. Some artists slightly change the color of the model and sell it as a separate model, thereby clogging up the search, this is inadequate in my opinion, let them provide all the colors within the same product, or make significant differences.
I'm not going to leave the site either, but I'm boycotting subscription, I won't participate in it for anything, and if you force me, I'll have to leave the site or raise prices above the subscription threshold.
