I couldn't personally ever see myself using an auto-bet bot to gamble.  That would take away the entire point for me.  I use gambling as a form of entertainment and by using a bot it would seemingly remove all the entertainment from gambling.  Then you would just be left with bad odds at earning back your money.  Why would anyone want to do that?  Even if it was slightly profitable, the risk and time wasted would seemingly nullify any gains you would receive.
