There's a difference between someone being a sceptic and someone just being an outright troll who is just posting alarmist threads to purposely rile people up. He's not saying anything new and is obviously just getting kicks out of posting fud time after time.
If, as you say, there isn't the will amongst the staff to outright ban users like freightjoe and btc-room101, then could we have some guidance on reporting their posts? I would never report a solitary post simply for saying something I don't agree with, even if I do think it is just baseless FUD. But when these users post 20 times in under an hour, even when their posts are somewhat on topic, in my opinion it crosses the line from discussion to spamming/trolling. Can we report all their posts when they do go on one of their spamming frenzies?
Again, it's purely down to opinion of you as a reporter and the mod that handles it. Only Globals and admins can handle reports in Bitcoin Discussion so it's likely going to be down to me, mprep and Rickbig on deciding what to do with them. They probably won't get marked as bad so will probably just stay in the queue unhandled like they are now. Whether you want to waste time on report them or not if they're not going to be handled is also up to you.
