Why am I disillusioned?
In my opinion, the whole stack exchange network has started to rot.
Moderators seem to be incapable of differentiating between abusive behaviour and defensive behaviour. As a result, they have been allowing abusers to run rampant carrying out their attacks unchallenged. I personally have observed and experienced numerous instances where moderators actively participate in abuse against users merely trying to protect themselves from the abusers.
This combined with the company's promulgated efforts to retain users seems to have resulted in a misguided desire "protect" new users at all costs.
Sadly I have serious concerns that a once-great network of sites is headed to self-destruction.
