Thank you for taking this action.

Not that I know of. I don't think that the gmane mailing list archive 
currently poses a significant security threat.

I think that there are two issues. One is security (spam, etc.) and 
the other is exposure. I understand that the tz list is public, but 
this new archive exposes the tz list content to anyone with a web 
browser. For example, all tz list content can now be searched for on 

This is a big change. I think that this very dramatic increase in 
exposure will eventually have a negative affect on the list. I have 
seen this happen to other lists. Right now the tz list is very 
focused and low volume. I like that.
