There is a difference between unprofessional and just outright toxic. I just tried it out and for our company with over 2900 members it was sparsely used and most of it was just outright insults with little to no discourse minus one or two decent threads.

I fart and scratch my balls with abandonment when no one is looking.

To use such information as an indication on how I may behave in a professional environment is insane.

This site (admittedly from a quick look) seems absolute trash.
