Farcaster

One thing I really don't love about Farcaster is that there is cryptographic proof of every dumb thing I say.

It's not only a matter of feeling uneasy with this feature. It's actually against the GDPR-rules which include 'the right to be forgotten'. Suppose you post some fake and damaging info about another person, it would be hard to actually delete it even if a court would order to do so. That being said, stuff published in print is also very hard or impossible to 'undo'.
