While I’m sure there are some recent articles that touch on the darker side of MU*, I always look to this one (written by Julian Dibbell) outlining an atrocious event that happened on LambdaMOO:

TW: sexual assault - http://www.juliandibbell.com/texts/bungle_vv.html

I’m terrible at summarizing so I won’t really try, but it does a fine job of sharing a terrible event, how it affected people, and the changes that happened after. It also touches on what it means to make a society and shape a culture in this shared hobby; for as terrible as the event is, it’s also heartening to see how things can grow and change through player influence.
