My sympathies - I had to do that on Reddit and it was an enormous relief when I finally stepped down and was able to block a particularly onerous troll (who was mostly fairly helpful to the community itself, just singling me out as the only mod to receive his ire - I had offered to make him one but he turned it down). I hope you are able to preserve your sanity, b/c your mental health is important too, as well as all those that you protect from people’s toxicity (from whatever instance it may derive from). :-)
