I feel there has been an increasing lack of understanding/respect(more so the latter) concerning what kind of posts are appropriate for which subforums. The way I understand it is
Serious Discussion - for serious discuss of topics
Random - for more lighthearted yet still coherent discussion of topics
IB - anything goes
I think this is a good model. There are subforums for all kinds of posts.
However, I do think it is a problem when incoherent memes involving the wikipedia article on corn or lyrics to a certain Yes song appear in Random or SD, either derailing legitimate attempts at discussion or polluting the thread list with threads that would likely be of little interest to users browsing those subforums.
Furthermore, these posts are often by longtime users of Fakku who are aware of the rules and should know better. If these users want to post memes or troll, there is the entire subforum of IB that they can utilize.
Negative reputation is not going to be a deterrent against this kind of spamming/trolling, so I am going to suggest that some other type of deterrent be considered.
Edit: someone else posted a similar thread to this concurrently.
