This worries me
The English Guy has a post entitled Google/Blogger Deleting Real Blogs that I’d highly recommend reading if you’re a current Blogger user or considering using their free service.
A thread at the Blog Party forum suggests that Google is targeting bloggers that have multiple blogs which link to each other. This is a tactic which many legit bloggers do and is a major part of how the whole blogosphere works. It is also a tactic that is used by sploggers. But that in and of itself should not be a reason to go on a search and destroy mission for all bloggers who interlink their sites. The logic in that is faulty – just because a tactic is used by sploggers doesn’t mean that everyone who uses that tactic IS a splogger.
So if you’re using Blogger and you have multiple blogs which you like to link to each other, you might consider porting your posts over to another system, such as TypePad or WordPress.com, before you wake up one day to find your blogs gone and have to go through the nightmare of trying to reach support personel (which has been reported to be very difficult) and proving that your blogs are legitimate.
Consider yourselves warned...
