I don't mind occasional form garbage, but I am worried about scams to insert code or backlinks through my contact forms.
I have several websites that use a simple contact form.
They are all on shared windows hosting.
They are simple HTML sites that post to an asp form handler provided by GoDaddy to send the contact info to my email.
My users are non-technical and have no reason to put links or any HTML code in the contact form fields.
Specifics would be VERY helpful.

If the forms are merely posted as email, then the links are harmless - you can safely ignore them.
You could set up rules in your email client to delete them automatically. For instance, delete any email that contains link=http url=http etc.
