I'm getting irritated with the watering down of the word "spam" to mean, essentially, "any communication I am not or do not believe I would be thrilled to get".

I'm getting irritated with the watering down of the word "spam" to mean, essentially, "any communication I am not or do not believe I would be thrilled to get". Spam is permissionless mass mailing. If someone has Liked a friend's band on Facebook, they've given permission for contact. If you're just not a fan of self-promotion, fine, say that, but don't claim that something's spam when it is nothing of the kind.
