The no sass rule frankly comes across as unprofessional and a vector to disregard legitimate criticism. That was actually my first impression on re-reading the rules after returning from a break in w11. I think sarcasm has a place in critiquing certain behaviours. Harassment should be banned for users and mods alike obviously.
I actually was considering putting my hat in to be a mod. I'm a pretty unknown player and could be non-biased between factions. I don't want to though, I think you need more clear and consistent rules and enforcement as a good foundation first. This place has been under-moderated for awhile and the community perception of enforcement is a mess. Consider a blank slate policy for all non-banned users, as we have players openly harrassing each other as it is, and its hard to tell who instigated it. I have the utmost confidence that if any players are indeed R-words or worse, they'll open their big mouths and get a ban for the privilege.
