Anon edits 

I dunno. For now I'd suggest just treating it as normal anon IP vandalism and just revert it as needed. If it's our persistent Baconian I don't quite see what he hopes to achieve by pushing that edit—it mainly just looks like a poor-quality edit to me, not his particular form of POV-pushing or disruption—and it could well be just some random visitor. If whoever it is keeps it up the next step would probably be trying to contact them on their talk page, followed by pestering some poor admin for advice if there's no reply. While I must admit finding it difficult to Assume Good Faith after the recent shenanigans, AGF is one of the core guidelines of Wikipedia; assuming sockpuppetry and deliberate disruption without more substantive indication than this would be premature. Or put another way, as yet it doesn't walk like a WP:DUCK. -)
