On the Vote Down FAQ page there is no mention of the recent change where down voting questions no longer result in -1 rep for the down voter.
What happens when I vote down?
When you vote down, you are moving that content "down" so it will be seen by fewer people.
- Downvotes remove 2 reputation from the post owner.
- Downvotes remove 1 reputation from you, the voter <-- should mention on answers only
- You can vote 30 times per UTC day. <-- now 40
Voting down is not something we want you to take lightly, so it is not free.
