I'm not particularly fond of the ACS. I was provided with membership by my work and started getting a large volume of email from them. Unsubscribing from their mailing lists was a complete ordeal[1], and it was impossible to completely unsubscribe online - I had to call someone at their office to get taken off a mailing list. In the end I gave up and filtered their emails instead. Despite the fact that my membership has since lapsed, I am still receiving their newsletter and invitations to various events that, as a non-member, I can't attend.
[1] I had to log in to their account management system, which involved finding a randomly generated username and password that had never been sent to me.
Exactly the same experience but instead of emails (filtered out) I get a ton of snail mail asking me to re-join / attend events, its probably been 2-3 years since i've been a member and I still get the mail forwarded to me from my old address
