About Flickr change
 

Do you get it what's going on this month?
They are going to delete pictures with nudity only if they are private but the public ones will bem no restriction??

These are the key points
 

"the ability to share restricted and moderate content will be reserved for Flickr Pro members. "

"we’re limiting free accounts to 50 non-public photos "

"The above changes mean that for free accounts, photos over the 50 non-public photo limit or any moderate or restricted photos will be at risk of deletion. "

So no restricted or moderate material for free accounts.

I think the interesting words are "at risk" and there is still a lot of this material out there on Flickr so I don'r know if they will be able to keep up with the serial collectors and re-posters.
