The mods are very active in some of the sections on this forum and I see whole threads being deleted on a daily basis. I lose about 3 to 4 posts per day, when they delete these threads.
It must be difficult to determine if a new thread is unique or if it adds something new, based on all the threads that has been posted on this forum before.
I've already told about this that I'm not really saying that all those same subject threads aren't worth making comments into, as few or many of them add up value and spice to the same subject by adding a whole new twist to the topic with a somewhat/completely different content in the OP, sometimes people who post in those threads don't watch OP or even first few posts, and they just try to add up more spice to the conversation by saying the same thing again and again (spam) which turns that complimentary debate into an unnecessary box of matchsticks which is left empty (even if full as it contains nothing but shit).
I made a little study of my own on these so called "spam" posts
~ Most of these posters never read previous posters comments.
~ A lot of them only respond to the thread heading and not the actual content of the OPs post.
~ The posters doing this, usually have a "language" difficulty
~ The post history of these spammers shows almost zero creativity or constructive posting.
Looking at this, you might find it difficult to change these people's posting habits or even their intellectual capacity or the lack of it.
