Extremely overbearing mods who will ban you for anything and everything. Don't get too attached to your account, one accidental misstep and you're likely to recieved a temporary, or even permanent ban with 0 warning. They employ a visible "mod trust scale", and I can only imagine this has caused much distress to kids who play that accidentally acquire a low one. Just cruel to do in a game directed towards kids.
Not to mention the overt homophobia. So much as mention that you have two moms or dads and you're out. Any mention of LGBT people, or even just pronouns, is strictly forbidden. This is disgusting. LGBT people aren't inherently not child friendly. It's obvious this is based simply on the mod teams moral views, not actually to protect young players. They allow far less child-friendly concepts to get through no problem. Hell, someone in my group found a wild horse with the game generated name of "Heaven's Gait". A reference to a suicide cult that took a number of lives. That's more acceptable for kids than someone having two moms is?
There's a reason this game has quite a small user base, only those who play it exactly how the mods want them to and never try to have some fun with it survive for long.
They also give out lighter bans for those who have purchased memberships, which seems unfair. I got twice the length of ban a friend did, who was actually involved in the situation we were banned for, while I had little to no direct involvement. I was largely just standing nearby. Only difference is that I do not buy memberships and the premium in game currency.
