Look at the profiles of the last five posters. Created in last 2 months. Start posting in off-topic/politics. Only post about CN coins, never about other coins.
Yeah .. the same type of horde was presented in the BCN thread, and also were heavily present around the shift from the BMR to MRO thread. Sockpuppets are a common occurrence in all of these threads. OFC you can say the same about mine; however, I have only one active profile at a time .. not that it makes a difference but it would be pretty awkward for me to use multiple accounts simultaneously.
It's fun to speculate why they're around though. Either BCN promoters, CN promoters, paid marketing competition from another altcoin, paid competition from a totally alternative group perhaps not relating to any currency at all, someone just bored, anything really can fit .. the main theme that seems to be present for all of them is that they usually post highly suggestive, non-targeted, potentially offensive, comments designed to be mostly passed over -- but noticed (perhaps unconsciously) -- in order to cause general confusion without inciting an argument. There were also some in the DRK thread, but IIRC they usually just copied and pasted previous comments .. but it can't be confirmed whether or not these are the same people.
Personally I'm guessing just someone's subliminal advertising marketing group .. but who's to know? Best advice is to just know when they're around and, after recognition, give a factual answer if possible .. so that anyone else reading the comments doesn't get sucked into the trap.
They're most likely all shill/sockpuppet accounts created and used by one guy, especially cause you see one of them go offline, and the other goes online right after, aka PizzaTraveler is online now, and all others are offline. It's really pathetic, but that's how some people are.
