Don't open the NSFW tagged channel automatically every time you enter a channel.
NSFW channels are to be viewed at the comfort of your home, while drinking a Gin and Tonic and listening to classical music, not when you're inside a crowded bus. Unfortunately, Discord, as default, remembers the last channel you viewed within certain channels, and while that's a great design idea, it becomes a flaw when that channel is a NSFW one and its contents are displayed for people who aren't prepared to see the classy content in such respectable safe havens
I've run into this problem so many times, the NSFW conformation should reappear. This would fix the problem.0
Yup, this could be fix the nsfw reopen problem0
