No need to take it personally. Bitching is a word used, when one is unable to understand criticism. Perhaps some people like your approach, but this might become a platform used by a million people, and the bot would be filling the chains in no-time.
Like I said, would be better to have a subscription-based service, than a system-wide "justice bot". In the end, you decide what is flagged and what is not. The abuse potential is huge, so it is a fair warning from my side.
So what next, adding my account to your DANGER list?
