It might be an efficient way of getting rid of a lot of spammy backlinks (not to say that there isn't some good stuff on blogspot too... but for many webmasters, they're an unlikely source of links).
I agree - 99 times out of 100, if someone on blogspot links to you, it's a bad thing. Is the 1 out of 100 worth it? No.
