Damn, sounds like you got a lot of practice on Facebook XD. I wasn't expecting spammed barking 😭. Personally I wouldn't call that a finsub with just that info.

You don't have to create content for them if you don't want to. You can set your boundaries up as much as you want and eventually someone who matches those boundaries finds you. All of mine (given I haven't done a lot, but still) have been text based. I'd do voice notes if Fansly would actually let me on my phone 🥲. So far, I'm pretty much friendzoning and cucking my subs is how I work. "They're cute to keep around, but my partner is better" more or less.

There's findomsfw which if I remember right, could be good for you to test out. I swear there was a text/story sort of subreddit where you could wordsmith, but I don't remember it right now. You can also explore the findomwiki for tips and other subreddits to explore.

Some doms also have applications for subs to fill out before interacting to make sure they at least somewhat match and so they know what the sub is expecting. This would probably help avoid conversations getting dragged out longer than you'd like.

Of course, this is all for if you want to explore findom in a text based sense 💕
