It's better to just downvote and move on.
The first part of my response was because it seemed like he was trying to lure the parent reply into a debate trap using leading questions. Not because I thought he was a shill.
I use Facebook. I don’t think I’ve ever seen anything I would qualify as manipulation in sponsored posts, as my sponsored posts are almost always product advertisements. So it’s not obvious to me what is meant by “manipulation” in the post I was responding to. I think asking for an example is quite reasonable.
It depends on your social network, groups, likes, and shares. Manipulators are always going to try to target people who want to believe their lies.
