Been on the receiving end of psychotic angry behavior Their aim is to destroy you, bully you, put you in a corner, for no reason, using all tools and knowledge they have on you These people should get help, and this behavior seen for what it is: toxic, harassment, unsafe
The best thing one can do is block and ignore, and when a new communication channel opens, block again i regularly hear of others being bullied by them, it's the same pattern of behaviour with different targets it's white saviour complex and violent politics disguised
