The disclaimers are BS.
If they think you are worth investigating, the disclaimer isn't going to protect you.
And I've seen disclaimers attached to grows that are like, a plant in a computer box, that the FBI is not exactly going to waste time on.
You generally need to attract LOCAL attention to be in danger. If your grow is big enough to attract attention just by posting pics on the web, you should not be posting them.
Use your brain here. If you have say a couple hundred plants, you probably DON'T want to post pics that show all of them at once. Dig?
