by 'bot' I meant human bot
my theory on @kahonapharhai is still that he's a PDF team guy (possibly on a payroll too) and his 'job' is to non stop create threads and try and drive up traffic and thus generate revenues for this site.
what were the findings of your investigations ?
He has 2 negative ratings, which I could not trace who gave and why, and he has given positive ratings to people so if he was some machine that is highly unlikely. He seems to be fond of creating threads and if he was working for PDF he would have massive positive ratings which by the way are Zero.
