Cracking down on people sharing your shit never goes well for the creator. The more you push back, the smaller your audience is.
With this new sub model the artist won't see a single dollar from me. It's so anti-consumer its crazy. Sub for 1 month, get nothing. But hey if you sub for 2 ok, then you can have something outside of some preview pics. Sounds like some OnlyFans scam shit. I am actually surprised this is allowed by Patreon.
There are those who will pay and those who will never pay. You aren't stopping anyone by "cracking down". All you're doing is narrowing the audience that will find you. Yeah its annoying to see your stuff going for free, but a large majority of those people would never have paid for it regardless. All you can do is look at it as free advertising.
Hell, look at it this way. I had never even heard of this artist until I found F95. They scrub the entire net of their stuff and don't post previews of anything. I actually subscribed because of the work I found here. So this thread actually gained them a member.
However, I rarely subscribe for 2 months in a row because I only like very specific videos. I sub here and there when I see something I like. But with this 2 months in a row shit I won't ever give them another dime.
The artist should focus on actually learning how to advertise their shit properly. Every time a new video comes out I have no idea what is being offered. No previews, no trailers, no social to check out.
How would I know you exist?
How would I know if I should subscribe?
How would I know what you offer?
