Someone recently asked if there was a neat way to see where all of the now broken down subreddits moved.
Some moved to Discord, some to Lemmy, and some are somewhere else.

While it’s a massive pain for a lot of reaaons, it’s also an advantage in many ways, reddit went wayy down hill due to more and more people coming to the site
