Online Bullying and unuseful posts on Early Math

Hi Khan Academy,

Currently I went through your Report a problem and got great support for noticing bullying and words being posted that were hurtful to young users and has been taken care of this one situation.

Most of the comments are positive but I noticed right now younger users in the early math section specifically counting there is more comments which are from different users while the are mild they could affect other users. Is there any way we can monitor this more? 

I have been using the math section myself being older as reviewing and learning I will flag them.

Can we develop a system or algorithm that when the user flags the comment it will disappear from forums until a moderator reviews the comments.

Another is a basic word filter it may cost more but it would filter out the most harmful words.

Finally could we have not just in the computer science internet safety but also a section specifically for all audience's on internet safety teaching them etc.

Khanacademy.org is always a positive experience but I almost feel since users are hiding behind anonymous usernames etc. The younger users are to young to understand what they are typing with more awareness and education in online safety on khanacademy.org we may be able to create wise internet users.

Kindest Regards
