I think it's better if people don't plus frag posts insulting other players. Along with automatically down fragging posts that are posted by players they do not particularly like. There are a fair amount of people who bring out the pitchforks way too quick against anyone who makes a mistake, then proceed to hold that mistake against them for a very long time.
For example: You know how everyone loves Powah? He's a great player and from my experience and equally nice person. Well when he first entered this community he was ostracized because he was supposedly a hacker. There was no solid proof of this, but everyone brought out the pitchforks and pretty much railed the shit out of him until he eventually just proved himself as a great person and player. This also happened with kukkye, a top-level EU scout.
It's obvious that this type of poor attitude is contagious, but the irony of perpetually responding to shitposts with insults is that you are actually shitposting and derailing threads even further. It's so much easier to straight up ignore awful posts as well than start a public argument with someone you already think is an idiot. Sorry about the random PSA but I feel pretty strongly about this type of "bullying".
