I had over 1600 links to a fairly young site. Yesterday I did a few edu and gov backlinks of which some had PR 2 and 3. I pinged them of course as well. Today in webmasters tools, there are no links showing to my site. Has anyone had this happen and what do you think will be the result? Most of the links were from a Xrumer blast but a lot of them were from manual bookmarking and forum profiles.
