Goblin
A goblin or goblins is a derogatory term for a falsely accused internet troll or community of trolls. The user of this term intends to disparage an internet-based community by FALSELY implicating that community in some type of "mass trolling" event or harassment campaign (such as mass disliking a post on an internet platform). When used correctly, the accused community must be innocent of the claim of mounting a harassment campaign (thus, falsely accused).
"Those goblins mass disliked my post!"
"...But there's no evidence for that based on your like-dislike ratio."
