Somebody hacked many sites and put links to my sites in hidden div

[zarades]

I had 300 good natural links to my site from different sites and site ranked great for my keywords.

Somebody (I suppose my competitor) has hacked other sites 2 days ago (checked Google cache) and now Yahoo Site Explorer shows 600 backlinks. I've checked new links - they all are in the same hidden div block - top:-100px; position:absolute;.

I'm afraid that Google may penalize my site for these links. I'm contacting webmasters of these sites and their hosting so they remove these links.

Is it possible to give Google a notice that these links are not mine so it could just skip them not penalizing me?

Is it safe to make "Spam report" regarding links to my own site?

So somebody else hacked websites to place links to your website? Crazy.

I doubt you'll be penalized for the links - the links will probably just be discounted.

Discounted? Maybe. Penalized? Not sure.

Google will have a hard time reading the intention of these links. How can they be sure these links were placed by the competitors of Anton rather than Anton himself?

Sites were penalized today - they cannot be found even by "SITE NAME" searches. I'm making "Reconsideration Request". Can I do anything else?

[AdamThompson]

The sites that were hacked were penalized, or your site was penalized?

[zarades]

My site was penalized

I'm following up on older, unanswered questions in Q&A. Can you tell us whatever happened in your situation, so anybody else that's in a similar situation might get some advice? Did you recover, or is this still an issue?
