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 thread that's not been replied are categorized as spamming ? or the thread have been posted by someone before ?
When a topic is yet to be replied to, it doesn’t mean that the topic is refer to as a spam topic but maybe the right audience are yet to see the message and engage with it, or not just a topic the person have something to say about. Spamming means more to what you’re saying and as you’ve also explained in your topic, meaning bringing up a topic without relevance to a group of people which they find uninteresting and deviating from the point of view in that section. Any topic created without the context of it not solving any issue at hand there, should be regarded as spamming and not to be tolerated.
Again what's off-topic all about?
Off-topic may be similar to spamming but they’re some off-topic discussion that you won’t call spamming. Posts in off-topic are moved into the section if it has no relevance to the board it’s been posted on. Your post may be making a lot of sense but if it doesn’t match the kind of discussions needed on that board or any other board in the forum, it’ll be moved to off-topic, such posts are regarded as off-topic posts.
