I agree with Toby. Time and worry is better spent on other things.
I've joined affiliate programs and didn't promote them for years. Sometimes we forget or something comes up.
I've also joined affiliate programs and didn't begin sending traffic yet, and was informed my acct deleted, and then just killed any desire or want to help or promote that program ever again.
This is the internet, and those affiliate join pages are setup for us to join automatically at any time we want. I think we should be able to promote any time we want too. No pressure is better imho
