As the other person that replied indicated, *key is shorthand for Misskey and Misskey fork instances like Sharkey/Iceshrimp/etc.
There's a bunch of them and since many of the instances with primarily English or other language (besides Japanese) people on them aren't using Misskey (or any specific fork) it's easier to write *key.
I should have clarified that in the OP, but I hoped the body text would help with that. My bad!

This is you right now. Most of us have no idea what Misskey is.

I was more commenting on the fact that it’s an incomplete sentence. What does it have to do with Lemmy?

Lemmy instances (verb) with *key instances (noun).
Threw me off too.
