Yeah but imagine your luck if you were searching for a 30 year old dude who uses Linux.

The ratio of :3 on Lemmy tells me its mostly furries and transfems. In otherwords, a thriving online ecosystem. So there is a decent chance this has better odds than most dating apps of having interesting people.

They are a privacy nightmare and also trying to milk you for profit.

They have little to no incentive to find you a partner, they want you to keep using (and paying for) the app. They profile you, they sell all your data and to make things worse there are four(-ish) large companies running it all. They offer multiple apps and just combine all the data in large databases. I would argue they are worse than regular social media, given you share intimate details about you on these apps.

Also the lack of Arch-using cuties in my life. That problem might also be addressed.
