I am willing to bet (but not to spend my time on this) that of all these backlinks probably at least 40,000 are blackhat sites. And I think it’s likely a lot more than that.
I’m not so sure that quite that many links are black hat coming to you. For example, you have 8,540 posts here at CAP with a link in your signature, which gets reported as 8,540 backlinks. Knowing that you post in other forums quite a bit as well, that may be where many of these links are coming from. Not to say that you aren’t under seige by black hatters, just not quite that much I guess.
