I do agree having too many pinned threads can be distracting when viewing forums but it can be difficult to get the balance just right.
For example, the first link you provide may be old but it contains valuable information on finding upgrade offers and bonus content so this one needs to remain. The second link is clearly out of date and has been unpinned.
For the other pinned topics we will review them and try to remove any out of date links.
Thanks for bringing this to our attention.
