She doesn't post much, maybe once a week at most, same with sending out PPVs in messages. PPVs are usually $15-$30 pretty similar to her wall posts, maybe a few pics and videos less than a minute.
Not sure if she does customs but based on the subscription price it's definitely expensive.
She's so damn sexy but honestly it's not worth the price.
Apparently she's also an escort. There's some detailed story on 'the other' forum. If what he says is true, OF is not her main source of income and she can allow herself to run it like she doesn't give a fuck.
