I have only a single comment page on my site. The comments are moderated.
One person keeps leaving the same bulls*** comments trying to create links and I keep deleting them. Sometimes he even uses Silverstripe blog tags e.g. [url=http etc. He always uses the same sequence of letters so I know it is one person.
Can I configure the comment form itself so I can add REMOTE_ADDR from the SERVER array to the submit button action?

I really like the moderate feature so I would prefer not just generate my own comment form page in its place.
