why is there a limit to the amount of questions you can answer in one day?

As a level on users you are limited to

Posting five questions a day
Posting twenty answers a day
Posting ten comments a day

Users of lower levels , these being levels one to four have limited access to restrict and prevent abuse and spamming of the community forum.

The higher a users level the more they can participate a day as well as unlock extended yahoo! answers features such as the thumbs rating system at level two. In this respect having limits is also motivation for users to gain higher levels.

All the best

You have reached your daily limit,There is always to morrow.When you reach level two,You will be able to answer more questions,And vote.

They have to give other people a chance. It is also according to what level you are in.

Questions come in numbers please not amounts.

it depends on what level you are. For level 1 like you, you can only have 20 answers per day. i don't know why they have that kind of policy
