Spam links - which link is most damaging to my rankings.

[A.Ronny]

I have just started using Open Site Explorer and discovered a lot of spam links to my website.
(I have mostly ranked on page for many years one but in the last two weeks ranking have dropped to page two)
The links have Anchor Text such as Scam - Dishonest - Drugs. Most of the of the links are "nofollow".
Will links with "nofollow" affect my ranking and if so which of the links should i priorities to remove?
Do I look at  Link Equity - Domain Authority - Page Authority or other criteria?

Many thanks
Ronny

Thank you - I think i will try to remove as many as possible, and then disavow other they cant remove.

I would disavow them also.  Matt Cutts commented on this a while ago and recommended in essence " any doubt" disavow.

Do this via GWT. (edit Added) Google Webmaster Tools

Now technically No-follow links should not affect your site however I'm not convinced that they are not used as some sort of signal plus if they supposedly are not used they shouldn't matter if you remove them (especially if they are doing you site harm). remember though if you remove follow links its a good idea to also counter the removed links by creating fresh links so you don't have a a deficit.

Short answer - No-follow like shouldn't affect your rankings. (but you can still remove them if you think they are harming you)

good luck.
