I wonder how much of the risk could be mitigated by simply disabling the private message function of microcosm? Surely having reports button help moderating the "public facing part" of a forum?

Having said that, thanks for all the work you have done. I was (and maybe still am) a member of lfgss although I mostly lurked once in a long while without logging in and barely commented over the years.

It is sad to see all online communities slowly migrate to discord, reddit and other walled gardens.
