What to do if some one intentionally placed bad links to my domain?

I have heard that google drops the rank of websites having links from bad websites. What if someone intentionally made a huge amount of such links to my domain name? Some suspicious websites are already linking to my website.

Hmm? I would think Google would have some kind of safeguard against that as there would be a lot of people trying to jam up the opposition? If I were you I would contact Google about this and maybe they will see that truly happening? That is only my opinion.
