We have a number of questions about Flickr where the answer was essentially "get a Pro account" - I trivially found Can I download all of my flickr photos after the expiration of “Pro” subscription? and https://photo.stackexchange.com/questions/3445/how-could-i-prevent-involuntary-resize-of-pictures-by-flickr, but I'm guessing there are more out there. The answers were perfectly correct when given, but with Flickr having pushed almost all the pro functionality into their free accounts, the answers aren't really helpful any more. What's the best thing to do with this sort of question?
One possibilities I see would include posting a new answer saying "not relevant any more" and hoping it gets upvoted, but is there anything better we can do?
