Minnowbooster is definitely not a bid-based voting bot. Bid based voting bots split up a 100% vote every 2.4 hours between everyone who has sent in a bid in that time. Minnowbooster gives a fixed value upvote right away.

Please let me know what bots you feel are intentionally scamming users and I will review and remove them from the site if I find that to be the case.

The removal of the max post age column was an accident and has since been re-added.
