Spam doesn't HAVE to be "SHORT" pointless annoying messages. About a month or two ago, I used the word "lpam" to describe "Long Pointless Annoying Messages". This occurs when you have a very long, rambling post that says nothing in particular about the topic. Other forms of spam may include double posting, off-topic posts (i.e., replying "hi" to everyone on a topic), and plagiarizing (copying someone else's post and replying with that exact text, just to annoy them). So sometimes I refer to SPAM as "Stupid Pointless Annoying Messages".
