i mean i will penalized by google?

why do you need to hide the links ? and why do be penalized by google ? one more important question here ... what experts ?

this place is turning in DP

no no.. i don;t want that the competion see my links because are free..and if they will build links like my they will be higher then me in google.
i mean some of my competitors have 100k to 1000k inbound links. i have like 7k but rank also at good at them..

I think that is not possible my friend, you can't hide links, if you hide them using nofollow on them you'll never receive link juice.

If you're worried for your competition just be more creative.

uff mondo try to read again.
yahoo site explorer shows 1000 links...i asked how i could or from where i could get some nofollow links to cover the ******** links because if my competion see the links they will build their own and outrank me.

Never heard of a no follow rule for a particular search engine only. You may be able to get away with it using your robots.txt file with specific rules for Yahoo's spiders but that will apply rules to pages not links on pages. I'm not too sure I fully understand your question though.

Is that you're worried that your competition will use Yahoo to see the links that are linking to your site? If that's the case then you're S.O.L. unless you want to remove yahoo from indexing those pages containing the links.

I wouldn't worry about it. SEO is a constant process. If and when your competitors start to take advantage of what you've done with respect to implementation then simply move on to create better in-bound links from pages of relevnat content and higher page rank. Someone else said here to be creative - look at new techniques. The 'link wheel' would be a good place to start.
