This is great but the SEO company will simply use Google's disavow tool to pull the link the week after you respond, they'll even include your response as evidence of you not cooperating.
I wonder if disavow / non-cooperation with this kind of stuff becomes a signal for the PR algorithm?
Verified, although if they are doing this proactively like the original email suggested, it's not in their best interests to actually follow through with a disavow. Generally only do that when already under a penalty, meaning this might be a tiny smidgen of a little bit more likely to work.
Though I do think it's a little overpriced for comment spam. Might actually get bites if the price drops.
The site in question is actually abandoned, and has gathered a LOT of spam. If I could actually be paid individually for removing spam comments, this could be a business. ;)
What's funny is, these are the same people who a year ago wanted to pay me to add their links to my pages.
