Thank you. You've articulated a common flaw in almost the entire comment-based internet. I'm an idiot and come here to learn, from a genuine curiosity standpoint - that doesn't stop experts behaving childishly though. It's simply far too easy to chide or downvote whilst 'hiding' behind account names, pseudonyms, and by the same token a flood of mob-rule can decimate curiosity in a matter of seconds. It's worse for kids. The best of the best is out there too, the well meaning, the guilty, the innocent, all at once.
The moderation is so childish on this site I just take their power away.
They are not actually good enough to fully ban by IP or anything else.
