[Solved] wp discuz causing high admin ajax hits and firewall blocking

Hello, I have been having a lot of issues with the wp-discuz plugin implemented as a comment feature on my learndash course. 

Issues mainly include ajax requests overloads which frequently cause MySQL to go down, ultimately bringing down the whole server.

Also, just today, registered users IP addresses have been blocked by the firewall is showing to be blocking a lot of requests similar to these:

I added the url path under a list of allowed url paths as shown and hopefully this can fix this problem. 

I would appreciate any insights or help with this matter as it has been really frustrating and also halting the entire student experience. Thank you so much!
