Ok, I have talked to Kristi and, yes, this means that if you use a deviant art link as your signature or post it on your image, this needs to be changed as they count as static links. 

Concerning older images, this new policy went into effect on the 15th of August. Therefore, anything posted before then can stay as it is so you do not need to worry about going back through your gallery and removing links to DA from images or descriptions that were posted before this date. 

I have upated the announcement to reflect these clarifications as well :) 

If there are additional questions, please let me know!
