Once you pay the subscription fee, you get direct message access, full access to general content although not necessarily every video click , and other perks.
Remember you are trying to build a thirst trap not a place for your friends to notice how glamorous your new purchases are.
If you have an new outfit you just bought and are trying it on to see how it fits, you might want to take a video of that.
There were even a lot of models who would setup cross promotion on sites like Instagram and Twitter.
So never use the term on the site and never share your OnlyFans link in any way on the site as well.
They will just move on because you have ruined the appeal for them of the thirst trap.
