Original post (June 24, 2008):
A quick search for myself reveals that I’ve been taken off the Google index (do a quick search for “david chan blog”), and I might know why. My guess would be that my Twitter Friend’s links appeared to be “spam” to Google’s crawlers. I’ve heard of people being penalized for link spamming, though that was not my intention at all.
My Twitter blog digest posts will be disabled until further investigation.
Update (July 7, 2008):
After investigating and confirming that I’ve been black-listed by Google, I have sent off a notice of reconsideration. Will update again when reply comes. Stay tuned – it’s going to take several weeks.

Update 2 (evening July 7, 2008):
Within about 12 hours of my Google index reconsideration submission, it appears I have regained my old positions for some search terms. I’ll need to do more checking to make sure that all my old posts have been indexed.
If anyone else runs into this problem, I would be more than happy to guide them through the reconsideration process.
Congrats on quickly getting off the blacklist! I’m glad it didn’t end up being a long and excruciating process for you.
