For now, I am intentionally not making it public who bumped each topic, since that way you can't prove that you bumped anything, and this may prevent people from selling their bumps as easily. I don't particularly object to making the approximate bump scores or bump powers public, but I didn't do this yet.
If you find bugs, PM me.
Can you at least make their own bump power visible to each user? Might help with debugging.
I think it will still encourage certain users to sell their bumping power. Like if one dubious member realizes that he/she has good bumping power. Nothing can stop him/her from PMing different project thread starters with screenshots that they can help them bump the thread for a price.
I think it's for the better it remains mysterious
