So (without slandering or whatever) I was thinking I could just develop a page that states "such and such is a scam."
It's OK to insert a small referer based welcome at the top of the page for visitors arriving from another site - so it's got to be OK to insert a short referer based warning, I'd think.
Have you checked your logs? I'll bet those links send very little actual traffic, if any at all.
