I really like solution 3, I hope that get’s implemented at some time. Though one potential problem is; what if pancakes@a.com is subscribed to pancaked@b.com and a user from e.com, who is defederated from b.com but not to a.com, tries to browse pancakes@a.com? Would they see the posts from pancakes@b.com?

If yes, that seems like a way to go around defederation, which I think is not a good thing always.

If no, how do you prevent the user from accidentally reposting something that they could have no way of knowing was already posted?

Different sites use different ways of calculating but often a user is considered active if they posted anything in x amount of days.

So all lemmy servers can communicate with eachother, unless a server decided to “defederate” with another which cuts the connection.

Futhermore, mastodon and other fediverse projects can also communicate with lemmy and back, but since the format of the posts and comments is a bit different this might take some work for the devs to get working completely correctly.

Oh well, just wait till inevitably reddit does something stupid again and those numbers will go sky high again.

Also, if twitter where to fail eventually and a lot of people join mastadon, I think the amount of people using lemmy would also go up because people get familair with the fediverse.

You’re on programmer humor, we don’t do “Brain” here.

Use lichess.org’s board editor

They have a completely different UI, so I don’t think that’s likely, but I might be wrong.
