Seems like a solvable problem though. We have a list of federated servers inately built into activitypub, right? Just need to tag results from those servers as being linked to a "lemmy" keyword search.
I'm sure I'm oversimplifying it, but all the pieces are there, just need search engines to be smart about how they index. Since there are a couple of federation based models that would be good to index, not just lemmy, it would probably behoove them to figure it out.
Yeah, Lemmy doesn't block you from accessing it via a VPN, for one.
