I was surprised today to see a post on John Chow's website stating that he has been unbanned from Digg. It's not just him either!
According to a post on pronetadvertising: Digg Lets Banned Domains Back In, a large number of previously blocked domains have been added back to Digg. This is very interesting as, in the past, Digg has always been steadfast in that once a domain is blocked it stays blocked.
This makes me wonder if this sudden change of heart may have been caused by a loss of data! Digg has been awfully slow lately. In fact another blogger did some math and asked the question "how efficient is Digg?" A question whose answer appears to be, "not very" efficient.
There is nothing on the Digg blog about this yet. If this was a database error expect those sites to be put back on the banned list shortly!
