It actually comes down Animal Crossing New Horizons Items to choice. Some folks do want to find spoilers, others do not. As long as people can choose whether they wish to see it, I do not think there will be any issues.
Thanks for the feedback. The main thing with megathreads is we have already got two running at a time (just two stickies is the limitation on Reddit): Simple questions and codes. Those are just two things that attract a lot of clutter, and there is a maximum of two sticky slots. Throughout the time something else is accepting that slot machine, the code or questions thread for example, would not be visible and it would get very little use.
A directory thread may operate, but frankly, in my opinion with a massive collection of megathreads is a bit messy/unintuitive. Just my thoughts though.
Another thing with megathreads that rely on pictures, there's no way to view pictures at this time, so the user would have to upload the pictures offsite themselves and place it. Which can be a massive hassle.
Can questions and codes be combined? People already post their codes in the questions thread despite the rules anyway. That leaves a spot open for a daily/weekly megathread for some other subjects. Or create the codes ribbon its daily/weekly scheduled article together with the other ones and maintain the questions thread. I think those threads are fine and all, although the simple fact that they take precedence over can you buy bells in animal crossing new horizons important news or events is weird.
