One of my sites got de-indexed and this has never happened to me before. I opened a webmaster account few minutes ago to see if there is a massage, and there isn't any message. I also wasn't sent a message to mail webmaster#domain.com.What does this mean? I didn't create many link, just a bit. Could it be a manual action since the site as getting 500 visits per day in a pretty competitive niche. Could it be a competitor?
