Was that forum link actually sending you significant traffic on its own? I tend not to think a single forum link (even repeated that many times) would do that much harm specially if the anchor text is your name or handle. I have a similar situation to that on one of my client sites; one of his employees participates (heavily, it would appear judging from the number of links) in a sporting forum completely unrelated to the business, but links back to the site with every post he makes. Doesn't *seem* to have hurt the site; I figured Google was just ignoring the links though they do appear in GWT, that's how I found out about it.
