Kathryn,
We are looking out for all our clients, including you, when we ask opted-out recipients if they think your message is spam.
I'll let you know that we're revising our AUP very soon. We'll communicate advanced updates well-before they are in effect. Again, nothing changed in the notice now. It's an awareness campaign intended to remind our users of the rules already in effect.
Essentially, when an account is identified as an abuser, we perform the same activity as AWeber. We don't want to encourage or imply that complaint rates get "customer solution" calls. High complaint rates are a major risk to the company and we need our clients to respect that too.
Like I said, we're still evaluating the upcoming changes in the AUP/TOS, in addition to a full suite of FAQs and communications for clients and prospects.
At any time, anyone may decline their acceptance to the AUP by simply contacting our customer support team and informing them you wish to discontinue service. We don't place customers in contracts, so it's a take it or leave it option for them.
Oh yeah, wanted to mention. If one clicks "No Way," it would just log them out. No instant-termination... sorry for the worry.

I hope this helps. Let me know if you have questions. My email address is joseph.manna (at) infusionsoft.com.
