Reporting counts as posting. I think deleting the red parts would solve it (I had to replace code tags by quote tags to make it visible).
It may worth mentioning that seaching and sending pms are also counted as posting.
If that red part is removed, users with activity of bigger than 100 will be able to use forum search engine multiple times and send multiple pms in less than 4 seconds.
I think the better solution is to change the code, so that reporting isn't counted as posting.
