It should come as no surprise that the lemmy.ml [http://lemmy.ml] admin team
took about 2 minutes to decide to pre-emptively block threats / Meta. Their
transparent and opportunistic scheme to commodify the fediverse and it’s users
will not be allowed to proceed. We strongly encourage other instance
administrators to do the same, given the grave threat they pose to the
fediverse.
I wasn’t aware of PGP, thanks for that info!
