I started a project called Issue-Bidder (<a href="https://issue-bidder.com/" rel="nofollow">https://issue-bidder.com/</a>) with the same concept before I even knew that bountysource (and meanwhile also tip4commit) existed.
I do not collect any repositories from Github but rather let the users manually submit a repo to Issue-Bidder. 
And at this point I think there is only one reason why bountysource does the opposite: For marketing reason – or better let's say this straight-out: the intention to make money. Guess what, the opensource community (speaking as a set of all specific communities) is a high potential and open market. Everybody is able to move mountains if you're ruthless enough. Let's just take this post on reddit as an example: <a href="http://www.reddit.com/r/gamedev/comments/2dsvme/someone_stole_my_gpl_code_from_github_showing_it/" rel="nofollow">http://www.reddit.com/r/gamedev/comments/2dsvme/someone_stol...</a> and I'm sure tons of other example cases exist out there.
In my opinion we can compare bountysource and all the other vultures out there with the financial brokers back in the 90' (why did I even set a filter to the 90' anyways?).
Should we now all hate them? Or are we now just hating around because we are naive and didn't restrict all our repos and do believe in the positive aspects of this high potential market called opensource?
