If/when there's a troll like this, it's not just mods who can keep track of social activity on specifically message walls, discussions, and articles, everyone can. so if you are interested in helping but you don't know how because you can't delete, that's okay, you can still help report and scan for activity because mods will be busy deleting everything already there. if you wanna help, the icon at the top of the screen that's like a lil zig-zag thingie is social activity, you can click and use filters to see message wall activity, page activity, and discussions activity so you can scan and help report more widely. that's if you are sure it's not triggering for you, but if you want to help that's a way you can :))
