You know, I love this idea. Since the voting system is architected to give the advantage to bots, it is perfectly sensible to then use a bot to do the voting even while doing basic interactions with the steem blockchain.

Now, the problem is that this is functionality that should be inherently built into one of the steem blockchain clients. If I could simply tell Steempeak, for example, that all of my up votes should be held until the 15 minute mark if they take place before that – then that would make interacting with the blockchain more efficient for everybody. And realistically, that's where this functionality should fit.

Likewise with the rewarding of content that's older than seven days old. That should be built-in as a feature to the client.

I wish there was a good way for me to get in touch with the Steempeak folks and have them touch base with you about integrating this sort of operability because it's exactly the sort of thing that makes sense as part of simple client operations and less so as a standalone system which scans the blockchain. That is a lot of content watching on at least one API server.
