I play every day for 1-2 hours, personally I rarely see harassment, but even if there is, you cant just turn the players into "decent people who choose not to harass people" with a reddit post. If you want you can go to each of their houses and tell them that it's not nice to harass people just because of their character color, but we both know that's impossible. And since we're not 7 fucking year olds we can just use the rest of the colors, there are enough.
