Hi, LJ!

We'd love to have a greater understanding of the issue you're running into. Could you please submit a support request in our Help Center? Here's the link: http://khan.co/KA-support.

Thank you for being a part of Khan Academy!

I'm unblocked already, but thank you for offering support!

I'm having the same issue, and it started last night and I'm still blocked. It says "Too many posts of this type in a short amount of time"

Same here! I want to know how long it lasts and how many comments leads to it not working.

Hi everyone!

We have a rate limit in place to prevent discussion spam and to help keep conversations focused on the course content. Most users should not encounter this limit through normal site use.

If you create a high volume of posts in a short amount of time, you will see an error message and will be blocked from creating additional posts until your limit resets. Depending on the type of post, this may take up to 24 hours to fully reset. For security reasons, I cannot provide the exact post or time limits.

I hope this helps!

How is tell that information a security risk? It would not danger khan?

If you were all making a normal number of posts (fewer than 100/day), maybe we are all experiencing the same problem.
