+1 for speaking out. It will help the community and perhaps help you too.
You need to chill. The community on Stack Overflow is generally very friendly. Being good is almost a philosophy on Stack Overflow. Users with a high reputation are assets to the community. These are the people who have moderator level powers and these users generally have excellent conduct.

Final version after being collaboratively edited
Stack Overflow is a collaboratively edited Q&A site.
As other answerers have already stated, the question seems to have been edited for clarity.
Did the user do right by removing the line where you ask people to not vote for bobince? Maybe, Yes.
When you ask a question, people post answers and if the answer is agreeable to other users they upvote it else they add their your own answers. **If you do not like an answer down vote it (or add a comment or just look away). **If you find a post abusive, flag it. While you may have the right to ask other users to not do a certain thing, expect them to exercise their right to do as they please. Bobince's question was not abusive and was in good faith. Your appeal to users to not vote for that question may have been in good faith too, but may not have looked to other users as such. Yet, George Stocker offered a bounty and waited for 2 days before offering the bounty to bobince (thus indicating that the bounty award was not to spite you for your appeal).
On your question, only you can mark a post as the answer. No one else can. Hence the selected answer on your question is what you selected as an answer and not what George Stocker awarded his bounty to.
Bounties are offered to attract more answers to a question. You can award a bounty on your own question and select a post to which you wish to award the bounty before the bounty expires.
Stack Overflow users can award bounties on questions asked by others. This is done if the user wishes for more answers to the question. IMHO it is a good and generous thing to do, because when a user awards bounty on his own question, due to greater views the user may reasonably expect some upvotes and thus some reputation in return for awarding the bounty (in addition to the expectation of a better answer). A third-party bounty giver does not have this temptation, he is in it purely for a better answer.
You can still re-edit the question and some other (sufficiently privileged) user can edit it again. No matter what happens the question will reflect that it has been edited and will offer a link to all the edits done.
The content you post belongs to the community in a good way. Stack Overflow uses a CC-by-SA license which makes your content available to others as their own, while still safeguarding your moral rights.
Finally earning reputation is not the goal of Stack Overflow, making available better answers to the community and making the Internet a better place is what Stack Overflow strivers for.
You have been for 2 months on Stack Overflow (with your current user account) which is a sufficient time to get a feel of how the community works, but it is never too late to learn.
As far as your allegation of removing sources is concerned, I couldn't find one, but it may have missed my attention.
In good faith...
