Hive has a good system with down votes and I've jumped on board, need to protect assets. We've had new legislation in Australia for social media which sees mainstream media and bloggers held accountable for defemation written online.
Alot of people took things too far, unfortunately I was at the hand of some viral bullshit defamation where my opposition was producing content that I assaulted and stalked women. Despite being in a long term relationship of 20 years, two kids and the allegations not being true there was no ability for accountability. When these statements are not only visible on mainstream social media but actual news websites it creates a false truth.
Social media will no doubt become a focus in time in more countries. I don't know why people behave in such a manner..
