Mi Yodeya has a bounty feature, where a user gives away some of their reputation points to either attract or reward a high-quality answer (simplified).
However, we learn in the name of the Chafetz Chaim:
You can't give up your reputation because it is not wholly yours to cede.
This would make it seem that using the bounty system is forbidden.
On the other hand, it could be that reputation points are a Bad Thing in the first place, in which case it might be beneficial to get rid of some.
What do the sources say about this?
