Here is an idea I would like to bounce. We could encourage people that care about the climate and/or environment to create an account and put some articles on their watchlist in order to keep them free from vandalism. My idea is that it is an easy way for people to do something. And since it is quite non-committal (they are not committing to correct or write anything at all right now, just possibly in the future), people might actually do it. And if the previous research stands, that as soon as people have taken the first step it is more likely they will be more involved in the future, this will be a pretty low hurdle to pass.
So would it make sense to make some campaigning material with this theme? And if so, what kinds of material would be useful?
