I've just reverted over 200 edits on the toki pona Wikipedia. Someone apparently feels the language is copyrighted so decided to replace every page, including user pages and the main page, with a copyright violation notice, presumably with the use of a bot. I've reverted these, although unfortunately the "bot rollback" failed on later pages so recent changes is a mess. I haven't deleted anything, so if people want to see the pages, such as "copyviopedia" this person created they can still do so.
As far as I am aware Sonja Kisa, the creator of the language, has released it under the GFDL, but I can't find any mailing list evidence to back this up.
If this is not the case, the wiki should obviously be removed but vandalizing hundreds of pages is not the way to go about this. I suggest we wait to hear from Sonja on the status of the copyright and remove it she can not confirm it is GFDL.
