I would never close a review comment thread. I would just exclude the offenders.
And the useless namecalling posts will be cleaned, once a certain reviewer has a chance to see them. Any posts with valid questions or comments will be left.
Exactally, regardless right now we want SKY to see what has been said for any counter comments should they been required.
We are not here to silence people, just keep the peace. Which, is precarious atm.
