Yes, it is a valuable recourse. But, Roblox is seeing it another way. I used to use them myself and used to make them, but since the captcha, they are broke.
There are things that is a security and community risk as to leaving bots able to rank people. A person could very much so, go rouge and demote all the people. There are many things that you can do with a promotion bot. (Even a roblox bot in general.)
You can kick members from the clan, kick members from a group, pay people, view audit logs, etc. There are some pro’s and con’s to the captcha.
In my opinion, I think there should be a lift on the needed resources to have the bot login to roblox to be able to promote, demote, fire, etc. in group.
