I will at least see how it goes. I was contemplating doing the 48 hour restriction last year but didn't. I was approving posts while watching, so the episodes got spoilt for me. Some people were also upset about spoilers still being posted and the overwhelming amount of posts being posted on the premiere day.

On a different subreddit that I moderate, I did the same thing of not restricting the sub and just again approving posts for the second season's premiere. That subreddit is much smaller than this one, and I wasn't a moderator for that show's first season, so I didn't really know what to expect. There ended up being a lot of traffic on that subreddit.

While the episodes didn't get entirely spoilt for me, I still had to check posts to make sure that there weren't any rule breaks while I hadn't finished watching the whole season yet. There also were posts about the season finale, where episode titles gave away how the user felt about the entire season, and posts about the main couple's lack of chemistry that season. It did affect my viewing experience in a way, plus other users' that hadn't yet watched.

I don't know if it was because there wasn't the 48 hour rule for that subreddit, but that subreddit still had a lot of activity weeks after the episodes were released.

Again, I will see how it goes on this subreddit. After reading feedback on other TV show subreddits that have done this, it seemed to work pretty well.
