Aren't we supposed to be able to ask and answer an unlimited number of questions at Level 5?

Yes they've changed limitations:

It changed 2 weeks ago.

There is 2 reasons it changed.

1) it is an initial measure to combat spam and other abuse.

Spam is consuming too much of Yahoo's resources.

2) it is designed to make a reduction in the 11 million questions with tied votes in the "In Voting" system.

Some questions have been in limbo for 4 years.

Another million is added every 6 months or so.

So now there is an increase in the allowance for voting.

For level 7 it is 400 per day.

The reasoning is that people can get extra points by voting for "In Voting" questions. Because fter they have used their allocation for Answering, they can still get points by Voting.

I expect both the Answering limits and the Voting limits to be tweaked again in the coming weeks.

Perhaps we will get 2 points for voting (on a temporary basis).

They changed the rules. And limits also apply to levels above. Read about the new set-up on the home page.

Some of the higher level players may have been abusing the privilege a little.

Yeah, they changed to rule to stop trolls (which solves nothing because the trolls just make new accounts, like they've always done).

No, I get restricted on my daily limit all the time.

... I don't know what's the matter with me..
