if it isn't legal, make sure yo don't give location away.. use a decent VPN. they can't track it back to your IP that way.
if it is legal, don't take pictures of greater-than-max number of plants allowed etc...
like someone else said. using this site is definition of not being discreet about your growing, lol.
I wouldn't use any real info until you win a contest. They had a metadata leak 1 and a half ago? but names and addresses are not difficult to find anyway. don't have to give a real name, obviously, but if you want something shipped to you, bwahaha, kinda have to give an address of some sort.
