[Foundation-l] Delete of Article History and GFDL

[Ting Chen]

Hello folks,

in the Chinese Wikipedia an administrator had deleted part of article 
histories. He deleted the article complete and then reversed the 
deletion of part of the historical versions. He did this in good faith, 
because he deleted vandalism edits and copy right violation content. I 
was the opinion that this is not a good idea because at first the GFDL 
requires the edit histories (also of the vandalism edits) and second 
because thus we lost part of the records about the vandals edits.

What is the right way here?

Thanks for any advise.

Ting
