Disney never said anything specific about this and this goes for any remake out there which is based off of past Disney, intellectual property. (Essentially, TTR's model pertinent to their policy on donations is being followed as that model seems to working for TTR and derivatives affiliated with the Toontown Online community, currently). *However and because of it's nature, donations remain a sensitive issue and - among other things - if a person is caught or found to be making a $money$ off of POTCO-related materials the general consensus is Disney would come down hard on said individual and/or project to the point to where their reach would affect those both directly and indirectly responsible.
(Note: I mentioned those indirectly responsible because those whom remain open to such 'entrepreneurship' and money to be gained via POTCO intellectual property could actually doom the community [as a whole] just as much as any specific project could if Disney caught wind that donations were exchanged. Unfortunately as it is, there do remains individuals out there whose own entrepreneur drive blinds their judgment and empathy towards the overall fate/happiness of others).
