I don’t think so. As far as I’m aware, concern trolling is an act to lower morale and place distrust among the opposing side. A person who’s on side B pretends to be on side A.

Let’s say you’re an admin on this site, and you have made a post asking for server donations.

Then just when all was going well, another member comes to the comments, who seems to support you and praise you really well at first. The rest of their comment is then telling everyone that they “appreciate your work”, but “you can’t handle it”, because this or that. Causing some of your genuine members to question you with their “concerns”

I’m on your side, so you should take my bullshit concerns seriously!
