We're all minor, recreational users here. With the exception of Dual, of course. He uses it for medical reasons. If the FBI really watches this place, we're only really breaking the federal prohibition law. If we were to try and traffic or sell across state lines, then, I'm sure, they'd start paying attention to us.
As you said, the information here is all circumstantial. Without photographic evidence or signed statements, what we post here is useless to them.
Besides, the rules I wrote are geared toward deterring fuckwits attempting to solicit the sale of illegal narcotics. The worst thing I'd allow down here is discussion on home grows. That's when it stops being recreational and starts getting into manufacture and possession with intent to sell.
Here's a fun informational poster for y'all.
