I hope you don't mind me offering my two cents, but I think you should look at you fellow staffers as well. Do they think that you're too much, or do they agree with you, but simply want to keep members around? As harsh as this might sound, I seriously think that the environment/site you're in sounds toxic. If your fellow staffers think that you're too much and didn't communicate that with you- instead resorting to petty things like painting you as a common villain, then you don't need to be on a site where you're constantly vilified by staff and members alike for attempting to be fair. If it's the latter, then I think the staff should re-evaluate what kind of members they are letting on the site.

I understand that traffic is important- hell, I always fret about not having enough posts per day or members going online. However, here's the deal-- if you can't find mature members that doesn't see you as a villain simply because you don't let them get away with their wrongdoings, you don't need them on the site. If there's a staff/member divide, there is evidently something wrong either a) the way the staff team conduct themselves, or b) the members are absurdly petty and can't understand fairness because their heads are too far up their own asses, or c) a combination of both. If it takes vilifying you to "appease" other members, then their issue will never be whatever flaw you pick out from them, their issue will always be you. That means you need to throw them off the site asap, because having no members is better than having a bunch of problem members.

While you might not mind- being disliked will grate on you. From your post, I don't think you did anything wrong, and it's genuinely concerning just because- well, you said that you don't mind, but it's evidently affecting you badly. As audacious as this sounds, I would highly caution against staying as staff wherever you are, or even staying, because the staff and member's mindsets/actions sound questionable at best.

Good luck Mori, I really hope that this won't be a lasting problem.
