I think MEGA doesn’t outright ban NSFW content, but your account can get banned without warning if it’s flagged or reported, esp if explicit or adult material is shared publicly. So, it’s best to keep links private. Email might be a good way to share; I need to check if there’s a way to automate that process.
Thanks for the suggestions, ruru! And yeah, the algo seems off right now. Even after the devlog, views are still pretty stagnant. I’ll keep an eye on the trend and see what happens.
