Is losing privileges after placing bounty OK?
Do not lose privileges once gained
As all know Stack Overflow has several privileges that assigns to the users according to their reputation.
Imagine this: I have 2000 reputation, I can now vote to approve or reject suggested edits. Meanwhile I needed to start a bounty because I wasn't getting any answer and just lost 50 reputation. Now I can't vote on suggested edits again.
And my question is: Did my sense of evaluation changed? I just offered 50 reputation, that shouldn't change anything in the privileges.
As the FAQ says: "Reputation is a rough measure of: How much the community trusts you; Your communication skills; The quality and relevancy of your questions and answers" so once awarded a privilege to the user don't remove it because he lost reputation by awarding bounties, that doesn't affect any of these 3 parameters.
