I don't think that I was boasting. However, if it being seen as boasting leads to more companies allowing one-click unsubscribes, then I see it as a good thing.

I generally don't just mark messages as spam because I don't want them in my inbox - that's what archiving mail is for (things which I don't need to see but might want to look at in the future). Spam is for when I don't want to receive messages and I can't find a way to get myself taken off of the mailing list after reading through one of the messages.
