No IM Activity Logging and no Email Notifications

Been running for several months and working well. After a lull in email notifications I noticed that there has been ZERO IM activity logging. My kid is constantly IM'ing. Also, there is only a tiny fraction of we\b activity being logged.

 

A check to inappropriate sites showed they were indeed blocked but no email notice was given no a log entry made.

 

Some sites were allowed through with raunchy content. Is there streaming filtering or is it based on 'known' sites?

 

Thanks.
