I'm just going to copy/paste something that I wrote elsewhere with some things removed/added for readability purposes:
You could consider using ManyVids as a place to offer customs. Payout is 80% on customs and they do cover chargebacks. I am moving my customs to this platform.
As x said, you're not really supposed to do customs on OF so this is a risk you would be taking, on top of the risk of being hit with a chargeback. Additionally, if someone wants you to say their name, this is something that you cannot resell so you could be making this vid for zero compensation and get into trouble with OF. I personally would not use OF for a custom unless it's under $100 and the person has already 1) purchased PTV's from you and 2) likes the PTV's that they've purchased.
As far as I know, OF used to be okay with customs. Many things have changed on the site over the past several months, including that. I used to do customs on there every week or so for specific people, but I've stopped doing them completely since I've been back from my hiatus. Occasionally, I'll do a short 5 minute "custom" where I just do something that I know the person likes, throw it into a PTV for $50 - $100 and tell them that I made them something special that they might enjoy. However, I do not recommend doing this unless you know the person and their likes/dislikes really really well.
