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?
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.
