I think there's already a feature for that if you have anything involving business.
It says "Public, to anyone who has the link", and I have my own private stream that only Kit knows about.
So there's a feature.
Sorry to break it to you but anything on this site whether posted on an unlisted stream or not is subject to moderation and must follow the TOS. Site mods can see any stream users create even so called "private " ones. Your secrets are safe however, I'm no about to go broadcasting what I find to the general public. Stick to the rules and you'll be fine.
Private streams should be a thing
If you ain’t gonna make group chats then just makes private streams; Private streams would be like any of stream but it would be invisible to anyone who isn’t in that stream
And the only way you can see and post in that stream is to get a invite link from someone who’s already in that stream
Since they are private they don’t affect any other imgflip users so site mods can’t mod it or whatever
So even if they are posting porn and stuff like that it would only be to theirselves
Also each invite link can only be used once like the memechat links so people don’t raid it
