As a counterpoint, I am apart of a "Good Karma Network" Facebook group centred on the suburb I live in and it is extremely wholesome and pleasant. The posts range from re-homing old furniture, organising exercise groups, posting local PSAs, to recommending dishes at local cafes and restaurants. There is never any conflict that I can tell of and there certainly aren't dubious posts about "suspicious" characters.
