On the Reputation & Privileges Help page, the section about losing reputation is incorrect.
You lose reputation when: : 1. question is voted down: −2 (-1 to voter) 2. you place a bounty on a question: −full bounty amount 3. one of your posts receives 6 spam or offensive flags:−100
First, there is a double
: after "You lose reputation when".
Second, when a question is voted down, the question asker loses 2 points, but the voter does not lose any points. Voters only lose a point when downvoting an answer, while the person who posted the answer loses 2 points.
All-in-all, I believe this Help page could be more helpful, however I did not see a way for the community to suggest edits. This answer on another meta question seems very detailed and should be considered a replacement to the content of this help page.
