IF you are going to post a review, please do not reveal spoilers, (I.e. crucial plot developments, or ideas that one would not know if they haven't seen the most recent episodes)
Why? you ask, when you post a review, it goes to the front page of the show's page, near the top, if one wants to watch the episode, they must scroll down over your review, and see the spoiler...
If you really feel you must post a spoiler, put that information in the title, and don't reveal the spoiler until the ver end of the post where it won't be seen by anyone unless the open the review to read it.
A better idea though just don't post it at all.
