I’d like to nominate @Mooncrest for Robbin’ Da Hood. I’ll admit i’ve had very limited interactions with this player who i believe is new. They’ve mainly been regarding shipping. But they’re really polite, friendly, and through. Seems as good a reason to nominate anyone 
I would also like to suggest that just as some deplorables have won Time Person of the Year, I see Player of the Month as more a badge of relevancy and impact, even if negative. In this regard I would like to nominate both CUOP (Prdgi if it has to be a specific villian) and ICUOA (They can nominate a specific individual if this is required)
Spoiler for bad Time Person's of the Year winners
Hitler, Trump, Nixon, to name 3.
I’ll cough up money for governor of the month next month
