...so that your request will still be meaningful after any links you post go dead.
Pal adds: this policy has been in effect since July 2013 and as of next month (July 2014) users who fail to attach a still image with their ID request will have a violation logged against them. Of course, this only applies where an image is available (you should cap a still from a video and attach it for example) ...if your ID request only has a textual description, of course that's not a violation. Thanks.
