So I've decided to start a personal SO version of "The Giving Pledge", i.e. 90% of my rep is going back to the contributors , 2-3K rep is enough for me.

Now obviously I'll contribute to the subset of questions that I could personally appreciate that belong to my skill set tags. So I'm going to give something like 14K rep points using the bounty system (not too many compared to many of you, but I was only active in a relatively small volume tag). 

I saw that there are several bounty related badges (Altruist, Benefactor, Investor) all of them bronze. I'm curious for the reason why there isn't an extended level for the "Investor" badge (*"First bounty you offered on another person's question"*).

How about a *Philanthropist* badge (or whatever you want to call it)? 
It can be defined as:

* Offered N bounties on another person's questions (N>10,50,100?)

or

* Given N rep points in bounties on another person's questions (N>10K,50K,100K?)

Your thoughts and feedback are appreciated.
