Would you recommend using such a blacklist? The main goal is to reduce request on my servers, because I see a lot of traffic is consumed by bots visiting my site.

You're better off using robots.txt to control the well-behaved bots, and request rate-limiting for evil bots. You can't use anything controlled by the client for badly-behaved bots, because they can modify themselves to evade your filters.
Generally yes if it meets your requirements/needs, unless there are specific conflicts you can find with their definitions and/or approaches. The prudent route is to monitor very closely during its initial implementation to ensure it fits your needs without introducing any unanticipated/unexpected side-affects.
