@johnjohnston I saw, I think from Engadget, that Flickr will allow Creative Commons photos beyond the 1,000 limit. But for anyone over 1,000 that person cannot add additional photos. So it is a grandfather clause, I think, rather than an exemption.
@ronguest also all uploads that have a CC license and was uploaded before 1 Nov, see <blog.flickr.net/en/2018/1...
