Full disclosure: i copy pasted the entire thing i believe from feddit, just supposed to not get me sued. Data retention is quite tricky for federated services since other instances could store things for longer than the home instance.

Since this is supposed to be a site similar to reddit, it isn’t planned to regularly automatically delete posts. I saw that Lemmy has a built-in IP address anonymiser so I think those don’t get stored at all.

I hope that this answer satisfies what you wanted to know. I’m just a guy hosting a monero forum and would never do any corpo privacy invasion bullshit with the monero.town data but the truth is that the instance is publicly accessible and on top of that federated so if anyone wants to scrape all the data, they easily could do it.
