I agree.  I think this might be MrDots best option atm.  Toe the line for a little bit with this game until a better alternative comes up, like one of the new sites that are being proposed. 
I also think that since this happened, MrDots is not naive to the longevity of porn games on Patreon.  I think he knows the writing is one the wall and inevitable that he will have to wait for those other options.  This is a way to bide his time, earn some income and keep developing, mostly Melody, but also some DMD on the side.
The biggest question marks on a new site are their rules, longevity, and payment options.  I think the speculation is right and that PayPal may not be the best option due to not supporting porn.  Thus a new site would have to have payment structures outside of PayPal, while using a system that is easily accessible in all countries.
