yeah i heard that the fail bin used to be public to everyone, except some people would still download them
not sure if it's true or not
Sometime around 2009/2010 it was removed, I think.
It was full of failed Add-On topics, where the Add-On was of piss poor quality, or broken in some way.
The links were left open on most things (removed sometimes on the most broken, or exploitative Add-Ons), which I suppose might have been intended so that people could pick up the Add-On and try to fix it, but it was generally just people using it for Add-Ons. After all, some of the craziest and silliest Add-Ons ended up there, even though they were broken.
However it did mean that there were ample topics in Help where people were complaining about issues caused by Add-Ons that had been failbinned.
So, Badspot closed the forum eventually. And then Ephi and Rotondo took to moving spam topics and posts into it, since I don't believe they had (originally) or have the ability to ban people/delete
