I hope everything will be resolved quickly. Saw a post on kbin about it, and I was just about to login my .world account and see what’s up. ~ Waiting on updates…
Tbf, I'm surprised this hasn't happened already. The software is not mature and is suddenly being exposed to a huge group of people. There are lots of eyes on it that weren't on the code before, and the big audience makes Lemmy a juicy target.
Other instances should be vigilant in case Lemmy could have an exploit until we know for sure what happened.
