It could be just me but I've been added, annoyingly, to at least 5 odd wordpress.com blogs in the last few days and it's a bit of a pain!
One that I imagine any WPMU users are also up for?
Any thoughts on how to limit the possible impact of the 'Add user who I've never heard of' issues while keeping the functionality? I think it'd be a worthwhile edit.
Cheers, James
