It's review bombing when some stoner Hollywood whore shits on old property and people dislike it.
It's not review dropping when they/them pronoun girlies with taped down tits try to ruin a small business by writing fake reviews (we know they are fake, as they are not even in the right COUNTRY to visit the place) on Yelp and Facebook, because someone claimed it was fatphobic or homophobic or some shit on Twitter.
