It really baffles me when people are targeted by trolls - trolls have been around since the days of Fidonet and BBS - without strict moderation it is a wild west.
Also the solution seems kind of obvious to me - just disconnect yourself - delete social media , curate your feeds and stop posting about your real life on twitter , your job or where you live and find another avenue not twitter to engage with.
4chan, kiwifarms - another site will just pop up to cater for trolls.
