One of my biggest concerns about Lemmy is the seeming inability to prevent astroturfing by various groups. I also wonder how it will survive when (not if) they receive GDPR fines, legal holds from law enforcement organizations, and a variety of other legal and regulatory topics that Lemmy (or at least the instance owner) is subject to even if the user base doesn’t believe that to be the case.

Hopefully the donation model will allow enough funding to address the realities of running a popular service.
