Well, on the point about internet anonymity, it is to be found. If you are only worried about law enforcement (or anyone else) tracking you down in real life, you should be browsing anonymously. Look up tor and privoxy and get the setup on your computer. You can browse, post images, download, etc., all while be routed through multiple IP addresses (making it much more difficult to trace you). So for those of you who are worried, download it.

On the point about pictures, I post every now and then. I do not grow pot now and have not grown for many, many years. I have a friend that grows and so I post pics of what he's doing. Since I do not grow, I'm not worried about law enforcement because I have nothing to hide. I have never posted a picture of my face because I do not want to be associated with them due to legalities; however, even if marijuana was legal to grow, I still would not put my face in pictures.
