Really sad... My moderators are crying for something like this! :(

unfortunately unless someone else makes one or ports it to work properly with 3.70 + then it's useless. Also I doubt we'll get the coder's input since he/she isn't supporting it.

The only reason this was not working with 3.7 is because the securitytoken fields need to be included. I have this working on 3.7.4.

If you want this to work, just download the files and following the instructions, but use THIS
product-ban_from_thread.xml file I am providing to import the product instead of the one in the zip.

All I did was make 2 little changes, which was just adding the two necessary instances of the securitytoken field.

Anyone have any luck with fixing this for 3.8?

Yep, It work on 3.8.2
tnx Kalina :D
