Bot's done, my turn...
I think just like most things, there is a place and a time.
I just posted the first of many suggestions For this Site.
An intro bot that grabs each new signup and directs them would be, in my mind a beneficial Bot. One that Votes, comments or replies for a person is Evil and must be eradicated.
In my New Sharing Village rules, I think it is number 4, states a tool or machine may only assist a Human, never replace him or her.
Directing Bots as above would assist, correct? and so no bug spray needed.
