Spam is posts that are useless for discussion and are usually off-topic regardless of what purpose they are made for. Spam also doesn't depend on how many pages the thread is if you really have something really factual to talk about and obviously post quality is something that counts, but since thread with 1000+ page are often considered a convenient place for spammers, then I think it makes sense for me to get it in the suggestions.

You can say I'm a spammer, that's your right, but if you really believe that I am a spammer what you mean. But I hope you don't neglect this one.
