Thank you for posting this - you are very right about transparency. There aren’t any clear online ethics (that I know), and while this suggestion is quite powerful, it’s all too easy for issue campaigns, particularly astroturf groups to take advantage of online anonymity. It’s also common for campaigns to approach social network “influencers” to host events for them. Again, if its on the up and up, great, but if not, who knows what would happen to offline organizing via social networks.
