yes, it's a bot. A complete explanation here : https://steemit.com/dustsweeper/@dustsweeper/dustsweeper-faq

You just send some steem or SBD to it and the bot will track your "dust" posts/comments and upvote them above the 0.02$. That way you don't loose all those small upvotes people give...
In the longer run I hope to give everyone who comments on my posts an upvote above the 0.02$... but I'm not there yet :-)

Thank you for the info. Will check it now.

No worries, you are doing an amazing job. Bigger upvotes will be just a bonus. 🙂
