Subversion in a Group

The goal is to go change the position of a group, by infiltrating a group, and using trolling tactics to sway the opinion on a topic. This is an extremely far fetch idea, but I think it could be done. There are groups for everything online, and they could be used to troll and influence without them even knowing. This way if one person, can influence the general consensus on a topic in a Facebook group and cause a bigger outcome, even though it is only one person’s idea.
