You may have already received a message indicating that you've been added to the "Wikimedia-l" Google Group; if not, you likely will soon.
In case it's not clear, this Google Group is in no way affiliated with Wikimedia-l, the Wikimedia Foundation, me, or anybody you'd ever want to be friends with.
If you do find yourself subscribed, I strongly urge you not to engage in any way. Report it to Google (not to me or the list) as an abusive subscription using the link at the bottom of the message, and leave it be.
If you find yourself being impersonated or wrongly implicated in this latest round of troublemaking, don't fret. Nobody will hold it against you, and in fact you'll have everyone's sympathies.
