they're trying to bait you in. throw doubt in the air like a trial lawyer. maybe you "say hmmmm." also clog up the board for any newbie investors to run away fast. so obvious. and then they have 2 screen names to back up their topic and conversation with follow up concurring. more clog. they're getting paid for you to respond. next thing you'll know, you'll get a pm from another saying the other "guy is credible I personally know him" ...
