That's a shame. I don't think I got that email yet; do you have the subject line? I actually joined ACM because O'Reilly did some sketchy stuff with my Safari membership a couple years ago. They sent me an email with an offer to upgrade from Safari to "O'Reilly online learning" with a discount for the first year, and the links were all going to genuine domains. But whenever I tried to actually do it, there was no way for me to see/do the offer on their site, despite being within the offer window. I wrote to confirm I wanted to use the discount, and asked for help, and they just wrote back and said "send us the email." So instead, I used all my download tokens (which also broke and required contacting support), canceled, and got an ACM membership for much cheaper. (Which I would have done anyway had I had a reason to seek it out.) Oh well. There is enough web content today that I don't think it matters that much.
