I'm going to say "no."

First, I'm going to recommend the Wheel of Time book series as it's a pretty good read. It's also a long read, and part of the fun of the series is how things are set up very early on that took years to come to fruition for the reader. The whole series took from 1990 to 2013. There was a lot of speculation on the internet about what a passage meant, and what it could be foreshadowing, and that was part of the fun, but all that material is spoilers now so if you think there's a chance you'll read it, try to avoid forums about it.*

Before the first episode of the show aired the showrunner said that he was going to "correct" some of the mistakes the author made. Between that and a leaked draft of the first episode there were some skeptical feelings about the show. Ultimately the show proved the skeptics right. Early episodes were different enough from the books that later plotlines from the books wouldn't have been possible if the show had continued.

The subreddit ran fine for years until the show. People were cautious about posting [Spoilers through X book], and other posters were good about catching slips in that area, there were threads dedicated to periodic rereads that could catch newbies so they could go through the whole experience from the start, so for an outsider to come in and start tossing bans, and then to track those people down and keep banning them was just one more reason the site as a whole went to pot. It's just one of the reasons I got to witness.

It'd be a tough series to put to TV anyway given how signifcant minor seeming details can turn out to be later on, even with a team that cared about the outcome of the product. They apparently didn't have that.

EDIT TO ADD: $RDDT has an interest in keeping large players like amazon happy. I wouldn't be shocked to find out $RDDT sold amazon a marketing package that included no bad publicity about the show.

• There may still be places where people can swap theories without spoilers.
