Well if she was getting business at that price good luck to her. She certainly wont be at £500 ph. And I would suggest that those that paid £300 have more money than sense. Its not like she's a knockout beauty at 10/10 is she.
If we feed these greedy SPs they will continue to charge and occasionally push the price to see whats out there. Her prices will drop. If we chose not to pay these daft prices they should drop. Its all about demand..... 
She is fundamentally a webcammer.
No doubt she will do face to face meets but at Piss Taking Prices
She knows this and is exploiting the fluffy cunts who desire her on webcam.
Plenty on AW take this approach and I hate to say it this will increase during lockdown.
Personally I prefer to wank over free porn, and if I wanted to I could fuck loads of decent pornstars for less than £250/hr. But I don’t (anymore).
