Mod Abuse:

The instance has 3 active subs, it's unlikely the admins are not also the mods engaging in this.

Banning anyone who downvotes is a clear attempt to foster a chilling effect on dissenting opinions. The mods and admins of this instance are putting their thumb on the scales in order to make their ideas appear more positively received than they actually are.

Thanks for your attention to this.

EDIT: the mod responsible for these actions has been caught voting multiple times using a variety of sockpuppet accounts.
