Personally I don't think this topic is relevant for Meta board. If someone like the OP is not able to understand the reason why their is archive & banned user then it is the end.
End of what? haha career of the OP. I think he should worry about it haha just kidding. The meanings of the words are easily understandable but like OP many people might not be aware of the difference in the context of the forum. That's why I think its best not to end it hehe. Overall, I think those who said, this topic don't belong in Meta but in the BPIP announcement channel.
I don't think it really belongs there, as the discussion is about the member status so. Overall its the decision of the Mods to move the topic. The simplest explanation to it has already been explained by the first replier. I don't use BPIP extension but once I used it, its a good extension.
