I am not even sure if this is still occurring, but in the past people could contribute a certain amount to the Sponge Patreon and get a title/badge here on the forums as a result.
Originally the titles were maintained manually to my knowledge(and probably still are if maintained at all), and as a result I would bet there are some people who still have theirs while they necessarily shouldn't(unless they're supposed keep it indefinitely) and some current patrons who don't have their title/badge at all. So I feel it wouldn't be a bad idea to go through, update these(or clear them out in their current state), and begin to use the Discourse Patreon Integration Plugin to make this process not as manual. It is still a work in progress it seems but it seems enough of the basic functionality is there. You can find it on Github as well.
Extra: Although not necessarily related to the forums it may be a good idea to advertise this Patreon somewhere and keep the actual Patreon page more updated than it is now. It just does not seem like it is out there at all and I can imagine there would be at least a few more who would happy support the project. A possible page for some information about Patreon could be on the Sponge Sponsors page or some similar/new page on SpongeHome.
