I feel like you totally missed the point here. The topic is making a bot to flag people who self-vote. This will never work because anyone can make a second account and just vote themselves from that account instead. Or, they can trade votes with someone else with similar Steem Power.
All this would do is make people create vote trading circles, or make people power down, transfer to another account so they aren't "technically" self-voting, then vote themselves up with their sock puppet.
The rest of your post is off topic.
