The events happen online are a resort to human inner wants. Because the online world, we can talk to many different people from far away and don't have to be ourselves. We can wear masks of what we wish we can become while others wear masks so they can be evil for once and not good like they should. Since the online world has little law too it (of course you can still get in trouble with the real law is you do some things) with people acting like they know everything, there is no stopping to it. Reason? Because we as humans, no matter how smart and how far we have come, have inner wants that we try our best to get even if it hurts others.
Simply put, we cannot change human will to wear a mask. But we can change how we do things with them. Complaining does nothing because only so few will hear and will just be a 2 day reminder. Not saying you're wasting your time, but it isn't going to change anything.
