I wouldn't go so far as to say she's scamming, but:
1) I would not recommend subbing.
2) Her content is not good (for OF, it's fine for IG).
3) Most (but not all) of her content comes directly from her IG. I mean directly.
4) She used to do PPVs back in the day, which also were not great but at least offered unique content. She hasn't done any in awhile though I don't think.
5) She's cute enough that it's truly a disappointment her content is not better.
6) The two pics here are IMO the best she's ever posted on the wall or in PPV and if you use that as a baseline just consider everything else is below this (of course, this is just my taste, your mileage may vary).
