If you comment on someone's blog, and need to give an e-mail address to do so, is it acceptable for them to subscribe you to their mailing list? (No notice is given of such automatic subscription in the comment area.)
I don't think it's acceptable. I'm not all that angry about it, but I'm minorly ticked and trying to decide whether to complain.
Update I did complain. The blogger responded that my winding up on zir mailing list was unintentional.
