You can write your topic however you want, but you need to answer these questions:
I see that Patreon.com is very popular between artist and different content creators throughout the world. I think Patreon is the perfect place to get donations to help boost your development studio or the developers working on your project.
I would hate to violate the Terms of Service so I wanna to ask on the Developer Forum if taking Patreon to Roblox as a support for getting development help on a game, is allowed. I would like to see if I could post it on my Roblox game’s description.
I know it would be violating TOS if I had something in-game but if it was outside of the platform, is it possible?
No. You can’t give in-game items for money, or ask people to donate with real money. Putting it in the description would definitely get tagged, and trying to get around it would get moderated.
Possibly, asking people to go there to donate would still be TOS. I’d never mention it on Roblox anywhere, and keep it something people can find if they look for it. Even then, I still wouldn’t be surprised if they moderated you anyway. You should probably stick to Robux donations.
You’re allowed to use it but you cannot mention nor link any rewards to it on Roblox. You’re ok with mentioning and giving perks in relation to social links like Discord or Guilded (which in terms of taxes and fees is cheaper than Patreon).
You’re allowed to ask for donations for a game- the only part against the Terms of Service would be connecting this third-party to the ROBLOX site, i.e. Game Description, etc. That would also include posting a link to a twitter post that includes the Patreon link in the Game Description.
You are allowed to post it on your discord, etc. BUT you’re only allowed to have perks that are not given on ROBLOX. i.e. no in-game perks from Patreon as you’re not allowed to trade IRL Currency for in-game currency/items/perks/etc.
In Short
You’re allowed to ask for donations, so long as the methods are 100% off ROBLOX.
Just to add here - if you plan on paying people with the donated robux or cash it out yourself, they’re non-devexable as of a few months ago so unless you plan on reinvesting the donations for ads, I generally don’t recommend it.
