Default protecting online forms

I seem to suffering a spate of attacks in recent weeks on a couple of sites that have online forms. The first involved email header injections from some spammer or other so I had to learn how to protect against them. That threat seems to have died down recently.

The second involves some kind of bot that locates online forms and fills fields with crud containing strings of URLS for sites peddling porn, pills or whatever...;-(

I think I've managed to plug any remaining holes but I do have one or two questions. Chief among these is that I wondered if it's possible - given that I do actually manage to detect spam of the kind described - to spoof a '404 document not found' response back to whatever is trawling the site in the (vain??) hope that it might not come back? Or am I whistling in the wind?

When spam is detected then appropriate action is taken, including alerting me by email with the details. So there's no real damage done but do I really want to know this? Might those primal instincts within that really just want to pick up whoever is doing it, hold them up to the light and shake them a little, be better off if they never knew in the first place? What do others think?

Meanwhile, I'll just go lie down in a darkened room and consider the options...;-(
