Oh and since when couldn't spoilers be posted in a review thread, they kind of go hand in hand and if people complain about being spoiled, tuff titties to them.
Since the thread title doesn't have "SPOILERS" in it.
Personally, I don't care about spoilers, most of the times, considering I need to read these threads before I get my book. However, some people might just be in the review thread to see whether they should buy the book or not, they might not want to be spoiled about certain details.
You could always start a thread with for spoilers.
