This is why I don't leave one star reviews as a part of a group.
Even if the spam detector doesn't flag it, there's often going to be some kind of back room deal going on with review hosters and rich "one star" victims.
Do two stars and list the "acceptable" reasons why. Don't mention anything that can be removed as a part of a "brigade cleanup".
Oh you had a completely legit review but ended with "f*** spez"? Guess what, the Reddit community manager can flag it and ask for it to be removed.
