Then you get banned from there. Or if it's a weather page they don't see your replies cause the posters block you. I look at some of the shares posted in CGS with my debunking alt and I see only "wow, beautiful sunset", I look with my other alt and see all the "does this look NORMAL to you?!?!?!?!" posts.maybe ? a better tactic @Dan Page et al can try, if they are so motivated, is to not post on the chemtrail pages but go to the "shares" and if permissions allow post questions on thier profile links.. this would also act as a deterant for their friends who might see the post and start thinking "chemtrails?, oh no!".
