1 million links can harm your site?

I have a client that bought a link for his site on a non related site with the anchor text for main KW. That site brought over 1 million links to my client's site. Now what should i do? Should i let the link there? Or should i remove it?

The age of the link is more than 1 year, and the link is placed in top menu, under the header.

At Mozcon one of the speakers (Martin McDonald) pointed 3 million links to my site. Nothing happened. It was as if Google already knew about his sites. But the good thing is that my rankings were not affected good or bad. Sounds like you just paid for links. Don't let G know about that.  If it's a legit site, keep it. If it's a porn site or something similar, I would think about getting rid it. If it's a strong website, keep it. Only you can make that call.
