The "What is reputation?" page has a broken link.
You gain reputation when: . . .
- one of your answers is awarded a bounty automatically: +1/2 of the bounty amount (see more details about how bounties work)
This link in the parentheses directs to a page that does not exist. I believe it should direct to "https://math.stackexchange.com/helpcenter/bounty".
This was fixed recently, across the network: 404 in Help Center for bounties
To beef up this answer (lest it's converted to a comment), I'll point out help-center tag on meta.SO.
To beef it up a little more, I'll ponder aloud whether the existence of Why are questions no longer being accepted from my account? means that automatic question bans are now implemented on Math.SE.
