I know I've been absent for a while, but it's been for good reasons. Unfortunately I'm coming at you today with a problem I've hit a dead-end with. (Furthermore, this may not be the right forum to discuss this topic).
When I landed my position last year to redevelop one of our client's webpages, there was a test form that was lingering around on the old website. Needless to say, I happened to delete that test form and any instances I could find of that code. The problem is, today, I'm still getting spam from that form.
The page is not indexed in our sitemap, nor in our htaccess. What additional steps should I take to resolve this issue?
