Have they tried...
turning it off and on again?
As in the site simply not serving those images for awhile, and then noting to enquirers that 'free' does have limits. 14 years and the users aren't amazed that the site is still there, might just need a little moola and 'free' has limits? It never occurred to them that they hadn't ever actually supported the delivery of their pictures?
Common sense has become noticeably rare.
