I can't describe other's behaviors. I only know about my own. You can't stop people from downvoting, and standards are just that, standards. Not rules or regulations enforceable to be able to fully stop them, but just guidelines to steer people a certain way.
How can you tell a newbie what is wrong with his/her stuff if they do not know the reason, good start eh
Haha, they should go onto reddit. I post rarely there(under a different username, rishi556 is my voting only account) and its 90% downvoted. Just gotta toughen up for the internet. Everyone is anonymous and nobody gives a damn about you or what you think. Just keep pushing. Everyone is trying to build THEMSELVES up and some of those people don't care about bringing others down. Best thing to do is stick to your social circle and enjoy things with them(its what I have my twitter for, other than VERY few crypto related things, its just some close friends).
