*nods* I didn't really mean to suggest that they might have maliciously subscribed people nonconsensually. I get a lot of mail suggesting I've been randomly subscribed to newsletters which I've never heard of, and while some of them undoubtedly are deliberate spam, my feeling is that a lot of them are probably accidental subscriptions resulting from somebody totally other having forged spam in my name to their subscribe addresses and, well, arse/elbow confusion having occurred at the verification step.
