I know a boss-everyone-around guy on another site, and every time somebody even typed a typo the guy 'shouts' at you (or is it a gal?). Reporting him/her doesn't work, the site admins see the user as 'a well-respected order keeper of the community'. And the user goes telling off you for your very existence. Most of the times you know exactly what you are talking about (commenting on a book on a 'Worst book ever' thread, for example) the user PMs or quotes your thing and say you aren't being 'nice' or that 'The author never did that!' because he/she happens to like that author, and the author actually did that.
I'm not sure this is very relevant but reading the topic made me think of this:
The only thing I can think of that is mildly related was the time a fellow writer posted a journal in his writing group crying about how someone had said they didn't like the writing group itself. They didn't trash talk, just simply said they didn't find it as interesting as others did. The group owner went into a ragefit and posted a journal in his group, as well as his own account, and when I stepped in to say I thought he was blowing it out of proportion, he proceeded to call out both my own work and the other dude's, and say that his group was way better than anything we could produce, although I'd never had a problem with his group.
Nobody got 'pwned' for say, but it definitely opened my eyes on someone I had previously respected.
It must be true because my mum said my writing is the best thing ever and I'm so good at it so I must know everything and my English teacher really likes this one poem that I wrote and so I didn't pay attention in class and just kept writing poetry after that. Clearly there is no more I could possibly learn and I am an expert on writign and stuff
