Sorry I might not have made my point clearly enough. By remaining anonymous, the OP has shielded themselves from any public judgement or reputational damage. Seems hypocritical to me given the post they wrote is deliberately designed to bring about public judgement and affect the reputation of Nick Bostrom.
So I’m saying “if OP thinks it’s okay to make a post which names Nick and invites us all to make judgements about him, they should also have the guts to name themselves”
It seems a little weird to me that most of the replies to this post are jumping to the practicalities/logistics of how we should/shouldn’t implement official, explicit, community-wide bans on these risky behaviours.
I totally agree with OP that all the things listsed above generally cause more harm than good. Most people in other cultures/communities would agree that they’re the kind of thing which should be avoided, and most other people succeed in avoiding them without creatiing any explicit institution responsible for drawing a specific line between correct/incorrect behavior or implementing overt enforcment mechanisms.
If many in the community don’t like these kind of behaviours, we can all contribute to preventing them by judging things on a case-by-case basis and gently but firmly letting our peers know when we dissaprove of their choices. If enough people softly disaprove of things like drug use, or messy webs of romantic entanglement—this can go a long way towards reducing their prevalance. No need to draw bright lines in the sand or enshrine these norms in writing as exact rules.
