Migrants to IJ, 2007

I would hope that "maintainer is inactive on the service" means "does not answer emails, or email sent to the address we have bounces." Or possibly the maintainer deleted their account.

Before making any changes in comm ownership, I'd expect them to try to contact the owner. For a very long time, they were unwilling to transfer ownership even when the orig owner had a deleted account... I suspect that the reason they're doing this, is that the spambots have figured out how to sign up for communities, and those that have no moderators have no way to get rid of them.
