Well, we need to post on such thread because we have something to share and we have the idea that need to be heard by all; thus, we post on such thread.
Why on earth would you need to share your thoughts on a topic that has been inactive for months now while there are other new and ongoing discussions that you can be a part of? It doesn't make any sense. And its not even like the posts that are made on those threads are somehow constructive, but they are utterly useless replies that even deserve to be deleted.
However, most of the people trying to open this post were not all newbies, let us consider that there are ranks who erroneously open a discussion just for the sake of their bounty campaign. So, definitely, this information is for all!
In fact, what you said is not just caused by Newbie. Many high-level accounts will do the same!
I understand that some higher level accounts might do the same thing, but that is very rare to find. All I have seen so far have been newbies posting in those dead threads making them alive again. And, considering the fact that a higher ranked member would understand such a basic thing, I just pointed out newbies doing this because they are the majority behind this new kind of spam wave.
