To combat upvoting and downvoting bots

It sounds like a great idea, but I believe it would require more access to the boards code than the Volunteer Team is able to provide. I'll suggest it to the team though just for consideration.

I like this. It forces people to actually engage a little, and if it's spammed it will be easy to see what's a bot and test it.

That still may not fix the problem. If a post has 63 upvotes and 21 downvotes, that means the post at minimum needs 84 comments, that 84 different people to choose from.

The correct way to handle vote manipulation is to have one or more authorized users with read/write permission on votes so they can detect and correct issues, like Stack Overflow does. Requiring a comment in order to vote just leads to fluff like "+1" and variations thereof. When I open a thread, I don't want to scroll through a giant pile of useless comments from people who didn't have anything to say.

nice i check 2 hour later its from +3 to -60
