Pro tip: If you guys are friends with some of the women on OnlyFans, it may be nice to advise them to not change prices so frequently. Yes, everyone gets to set whatever prices they want, but if a client buys in at a set price, they shouldn't be upsold (just a few days later) on price for the following month...and then doing it again and again doesn't come across well to the fans. Also - and perhaps most importantly - when you make someone re-opt-in, it puts them to a decision, and you're going to lose some percentage of sales just from that alone. And even if they don't actively decide to quit, when the price changes and they have not re-upped at the higher number, the system kicks them. So, you lose an automatic rebill from a fan you may have had casually supporting you for 5-6 months, no problem.
That could be a flaw in the OnlyFans system, but if you sign up to see me at $7/month, then that's going to be the price you're locked into for a very long time. But, that's just me.
