I bought the Premium version in order to be able to prevent users from editing, deleting and spamming comments - but discovered that this part didn´t work at all. I´m using WP 3.4.2.
You are forced to choose Edit comment in order to be able to accept and reply comments.
The funny thing is that in edit mode (after been clicking on Edit comment) you still can delete and spam comments, even though you have not checked these capabilities(?!)
I have been in contact with the developer of this plugin and got some help, but it still doesn´t work as expected.
Pretty upsetting when the plugin doesn´t work as you expect it and that nobody has informed about this problem before the plugin is bought.
