The use of physical injury smacks of chain letter threats to keep things moving. In this case to move through their preferred channels using their keys. Some of these file names include words which are likely to get anyone using them unwanted attention from the authorities such as "ISIS" and "thermite"... or even "SUMOP" which might get flagged for "summit operation" or "summer operation." At Best this is a honeypot.
thanks for insight. I really had it all wrong. What you say makes sense about chain letter threats. I never liked those. I broke them all the time.
