You can earn a maximum of 200 reputation per day (although accepted answers and bounty awards are immune to this limit).
How does this immunity work? I have two scenarios to explain what I mean:
Day 1
- You get 20 upvotes.
- You get 20 accepted answers.
This will earn you 500 reputation, since the accepted answers are immune to the daily cap.
Day 2
- You get 20 accepted answers.
- You get 20 upvotes.
Now, will this earn you 300 or 500 reputation?
