The bid-based voting bots section lists all of the bid-based bots that only vote every 2.4 hours or so. You can try the Content Promotion services section for quicker upvotes, although I don't know if they will be within 1 minute or not.
I don't currently show which bots leave comments on posts and which don't, but if you just check some posts that the bot has voted on recently you can see which ones comment.
I don't know exactly what will be in the next hardfork, but based on what has been announced it should not have any effect on voting bots. In general there's nothing that can really stop people from selling their votes.
i think you are right since steemit is all about freedom and these bots do help a lot to keep us minnows abreast with top whales and a good business option to gain some extra steem and sbd. thanks and i hope in your updates or upgrades you seperate those who comment from those who dont cos some use it to gain double by advertising in folks comment section which many of us dont find funny. thanks once more for your time and good works
