Conditions for retweet and auto following

Retweeting everything will not keep the quality of the bots that we makes. to justify this, some conditional fields will help. Like, ask for some words to filter. The same thing in the case of auto follow too... Let us make a condition for the bots we built to follow our followers or people who tweets about a specific word. I don't this its a big problem you you guys to code. because you have did a great job so far.
And another bonus Idea from my mind is auto reply feature, if someone sends my bot a reply, or direct message, let my robot to send him a pre-compiled tweet.
