I just received a a-mail from flickr stating that my flickr pro account is due to expire and that it would renew automatically. This is complete nonsense, as I cancelled my flickr pro account in 2013 - but I went to my settings there and yes, my plan was active and renewing automatically. The money is charged automatically too. It seems they have changed something (again) and it's messed up the system... So if your flickr account is still up and you ever had a pro account but do not wish to pay for it anymore, it might be wise to go and check that from your settings.
