I'm seeing a lot of these accounts on FM that are newly created with fake profile info and then instantly used to post messages that are superficial, nonsequitur, or entirely blank. Perhaps this is the way of the Net these days, with vandals and AI agents running amok. In the fashion of the Ignore List, I suggest a filtering facility per FMer where messages from fresh accounts can be supressed until the account reaches some stage of maturity (week, month, year).
