I remember when the Blizzard Overwatch forums used to have a vote up and down option, and pretty much when arguments went wild or someone didn't agree with something, you'd see a sudden string of dislikes even if the poster made a valid respectable opinion. Blizz since updated those forums (probably other ones too) and dropped the down vote button, but people soon turned to reporting the posts instead stating they were trolling or intent to cause problems etc. The like button is pretty fair though so don't think that causes as many issues as the OP thinks.

So long are the days when you could just post something and not have to worry about upsetting an oversensitive viewer...
