Googlebot was very active just before February 5th and immediately later. For about 5 days (10th - 15th) hardly any activity. Right now, Googlebot is spidering the entire site (again for the 4th time this month).
In 2001 one of my sites got dropped from Google. Google kept spidering the site. But I never got any more traffic from them. Even now it has 7,330 pages from the site in its database (just checked doing a 'allinurl: "mysite.com" site:mysite.com' search). Never get even one visitor from them. Quit holding my breath a long time ago.
