is it that any thread that's not been replied are categorized as spamming ? or the thread have been posted by someone before?
Yes and No, because a post is not categories as spam simply because people hasn't replied to it. It may seems the topic lacks the necessary ingredients to trigger people into discussion. And secondly, a topic can be considered a spam, if it has been posted before.
Bro you don talk well, and truly wetin you talk dy on point, but I just wan add to wetin you don talk already, to me oo the major thing I consider spamming is, in a situation whereby we dy discuss one or two things in a particular thread, you, you decide to give your own opinion, so when you talk, e no only dy off point but you keeps on repeating the Same thing wey no make sense in anyway just for attention or sending a link in a discussion thread repeatedly that has nothing to do with the discussion, to me na that one nai be the real spamming, because e really dy annoying , though some people dy do am intentional, while some people dy do am ignorantly, but na one major thing you need to avoid doing, so that them no go tag you a spammer.
