As more and more people migrate to lemmy from reddit (just like i did), how will lemmy adapt to the people coming in and the cost incurred for hosting it. I imagine as more people start posting stuff just like they do on reddit, the cost on the server will increase. And as lemmy doesnt have any ads or tracking or anything of that sort, how will it cope up with this?
Also does lemmy have retention for posts and comments?
What do you mean by retention? It has soft-deletion so data exists but is hidden; and due to the nature of federation, the deletion event can’t be guaranteed to reach and be respected by every server that was originally sent the data.
Oh so once stuff are posted on lemmy, even if deleted by a user, it can still exist on other server?
Delete requests are propagated to other servers, but in theory they can ignore that. So not really different from people scraping Reddit.
A good rule of thumb, is to assume anything you’ve requested or uploaded on the internet has been logged and saved by some third party. Really all one can do is mask themselves, so they appear anonymous. But otherwise we are all being tracked by the systems we are using at multiple levels.
Delete buttons might as well be feel good sugar pills. Even with GDPR and other laws in place, companies make mistakes and may discover they stored your information illegally for years after a takedown request is submitted.
