So we have a situation where a competitor is attacking our website with spam. We need help trying to uncover exactly who is behind specific websites. We've been digging through dns, sites with the same dns, backlinks, etc. Unfortunately we haven't come up with anything yet. Hopefully someone out there who is particularly good at this kind of thing can help us out. Thanks.
PM me the list of sites you are getting the spam from. I will have a look once and see if I can help.
