One of my site get hacked about a week a go. Before its happen i have 3700 bl in the webmaster tools. I have no back up so 301 redirect to my other similar site. Tke 2 days to rebuild the site. When finished i take of the 301. Today in the wm-tools show about 1800-1800 bl on both sites. On the second site i not builded any links. The main site lost 50+ position. What you guys think? All links come back to the main site by time or what?
