Just stumbled on the official google webmasters blog. I have been there before, quite a few times as a result of searching (as was this time). What struct me this time on this particular post was that OBVIOUS spam comments from March 14th 2007 have not been removed, even though later comments from the same author (probably SPAM also) have been removed ?!
Any thoughts ?
UPDATE (June 20th): Apparently the comments spam has now been cleaned, seems someone took notice of that!!
