I have many signature links if DP+other forums, i would have 10K+ signature links. i would like to add a new site new domain name recently. google would ban me? how can i do to be safe?
I do not think that signature links have enough power to bring you into the sandbox. But I do not know what happens if you add them as your first links. Why not starting as usual. First some links from social-bookmarking and those things. Then you can add the signatures.
same opinio as resident79. first some bookmarks and so on. wait a couple of weeks. then you can add it to your footers. perhaps also not all footers at once!
To be safe you should build your backlinks slowly for a new site, whether you chose to build backlinks from article submission, press release distribution, pay per post or signature links it's up to you.
