We had instances in the past where an image (or other user generated content) suddenly got popular in china or japan and suddenly exhibited the same behaviour as a DDOS but it wasn't; just many people sending eachother the link to it. We got some lovely bills for that and had to build protections for it. This was a while ago, but it was a PITA considering this was a little fun free tool we built with no intentions of doing that much work on it.
