Good day my good members of Bitcoin Forum.
As a newbie I must learn and ask.
There are some question I wanted to ask here but I was just going through some posts and comments just to understand  it better but still am still getting it twisted or i am confused,well my question is Spamming from my research:spamming is reefers to as unwanted messages,post and  comments sent to a larger numbers of people.
Furthermore,after going through the  Forum I have been seeing some posts and comments here in Forum,then I noticed many messages have been posted and none replied,is it that any messages that's not been replied are categorized  as spamming ? or the thread have been posted by someone before ?
Again what's off-topic all about?

Please my experienced expertise here highlight it to the best of my understanding
Thank you'll for providing a useful answer.
