Not really, no.
Said teacher had the nickname 'paedo' for several decades. It wasn't even thought of, really, his name was simply 'Paedo Blogs'. That wasn't some sort of 'secret' nickname - fuck, as far as the kids were concerned it was just what was on his birth certificate.
For that to be the case, don't you think that at some point someone in authority might have cocked their head and thought... 'hang on'...?
And if so, do you really think my school was unique?
I Don't.
From what I've learned then yes, they do fucking broadcast it. It gives them a boner.
So again - at what point do the Red Flags get raised? At what point does a poster with SE's history become less of a 'lol' and more of an 'OMG'? The posting history of him as a sexual predator with underage fantasies is all there, I'm not going to lay it out.
