There would be no need for review bomb if they were widely disliked. The issue is that they were not widely disliked and certain groups are angry other people consume this content.
This is circular reasoning. You're calling something a "review bomb" because you're assuming from the outset that its not widely disliked, despite the large amount of negative reviews suggesting it is in fact widely disliked.
Review bomb is when whole group goes out of their way to seek content they disagree and then downvote it. There is zero reason to organize all of that for widely disliked content.
However, especially right wing groups do it against mildly popular content they do not want other people to see.
What is a review bomb if not a symptom that something is widely disliked?
There are no review bombs on stuff that is widely liked either.
Typical review bombs go against liked content.
And to my original point, if review bombs are a symptom, then "verified reviewers" is addressing the symptom, not the problem. Same reason YouTube took down dislikes. It was around the time the Rings of Power was getting wrecked by LoTR fans.
