Honestly, dating apps are one of the cases for a federated system. Use whatever frontend you want, no one person owns the backend so they can’t sleazily monetize you. Probably would need to be a bit more cryptographic than something like lemmy or mastodon though.
With activityhub gaining traction, I actually think it's possible. You essentially self host your profile, which gets federated around. You swipe left/right, thereby accepting federation from a match of blocking.
Depends on how it is used. But I don't think it should be used for the matching process itself though. Maybe to help match interest (tags) between each other, like giving a connection score between two of them, but other than that, I see no other privacy respecting way to use that.
Moreover, on which data would we train on? I don't think there is any anonymized dating app dataset around.
Good idea. Let me know when you are finished so I can summon my army of catfish scammers, porn bots, and data skimmers. After we are break it we will than databreach it and sell all that wonderful data on the dark web.
The situation as it stands now you need a lot of security to run something like this. Which involves a lot of money. Which means you have to charge users. All these wonderful open source decentralized things only work if you can assume some level of good faith.
Most of the details are things that you might already know, or assumed was happening, but the article is a helpful resource for links, evidence, citations, and summaries
