I have a newsletter that users can subscribe and unsubscribe to. About 2-5 times a week I have some weird inputs coming from it and I cant seem to get it to stop. Im not the best at PHP, but I’m good at Googleing different solutions but I cant seem to find information on this one.
The weird submissions are usually in the form of “-1′” or nothing at all in some fields. I will include some images as examples.
The form is being validated and sanitized with PHP, it works when I test it out.
