Sorry for multiple posts, I couldn't tell if the sh .itjust. works post of mine went through and thought they were down too (also commenting here from kbin because i wanna not add more links to/from lemmy in case it could help this spread)
Assuming that this isn’t exclusive to the particular builds those instances are running it’s going to be a rodeo for a while. While I can see the desire to target larger instances it’s not going to be long before any instance is a target for the lulz.
Especially since doing that will let you Federate through compromised comments, and possibly affect other instances using the Federation network, unless they're updated.
