True. I have also noticed, since making this thread, that there is at least one California-based medical cannabis dispensary which has a WordPress blog, and has for a fairly long time. There is also a Washington-based members-only recreational cannabis club with a WordPress blog. So I'm assuming, based on this example, that our reviews blog should be on fairly solid ground rules-wise.
Mdtay11 also makes a good point. For better or worse these topics are a major part of the "world conversation", so to speak, at the moment, particularly for Americans and other countries where there is currently a lot of public discussion and debate about the topic and/or where the laws are currently ambiguous or (as in the US) outright contradictory (State vs. Federal).
If I were WordPress's administration - and I'm not, so this matters all of a hill of beans, but still, for what little it is worth - if I were, I'd be erring on the side of caution where censorship is concerned. The legal questions around this topic are very complex and, honestly, I wouldn't want to wrack my brains trying to figure it out. When the law of the land becomes clear and consistent, one way or another, I'd make a final policy decision for the site, but until then, I'd basically allow most anything to be posted so long as it wasn't unambiguously illegal or otherwise a clear policy violation.
Of course, it is also WordPress's right to decide the other direction and ban all such content, with exactly the same reasoning (ambiguity of legal status). And also just because it's a private site, technically, and the owners have the right to set whatever rules they choose for users to follow.
I am backing up my Smokefax posts, just in case, but so far, the practice -seems- to be to follow State law with regard to what content is permitted. (It's also possible that staff just hasn't noticed and shut us all down yet, but some of the few cannabis blogs I have found seem kind of old for that. Unless it's normal for TOS violations to go unpunished for long periods? I wouldn't know.)
In any event, happily, since creating this thread, I have discovered more cannabis-related content on WordPress. :D Some of it was started after I began this thread, but some of it I had just overlooked before. Still, there's less of it than I expected. Perhaps over time as it becomes more legally accepted (as seems inevitable, at least in America) it will become a more common or popular topic on WordPress.
