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 ?
Again what's off-topic all about?
Before I add to what others have said, I just want to advice you to not use AI for posting on the forum as I see you have already received a negative tag for that. Secondly, it isn't a must to post on boards that you don't have an idea about.
Write on boards that you can add meaningful replies to topics being discussed there. You should know that spam is subjective but any replies or topics that doesn't add any value to the forum or not necessary, can be considered spam.
We then have different types of spam as some can be managed but there are those that hurts they eyes to read and those are the worst type of spam. You also can be spamming when you now arrange your post them well like the spellings no too correct or the sentence them no dey add am.
Spam na just any unnecessary discussion to a topic (repeating what others have said too can be called a spam).
