# Limit max comments per user per day

Configure the **sn\_kb\_social\_qa.max\_comments\_per\_user\_daily** property to restrict the number of QA comments per day.

If the **sn\_kb\_social\_qa.max\_comments\_per\_user\_daily** system property is not set to the recommended value of `500` or less, then there will be no restriction on number of QA comments per day.

Ensure that the property **sn\_kb\_social\_qa.max\_comments\_per\_user\_daily** is set to `500` or less.
