I'd be skeptical. IMO all she's using AW for is to promote her OnlyFans.
She even admits on her profile that she's more likely to respond on OF, so just to contact her you need to subscribe to her page. Then it's no different to the many cam girls you get on AW with the escort box ticked, she's got your money so doesn't need to meet you.
It's also worth considering that there are fools on OF who will happily tip a girl £100+ just in the hope of getting a message back. When you're dealing with idiots like that, why would you actually meet one for a similar amount of money.
Obviously there's a chance I could be wrong, but common sense says ti's unlikely this girl is genuinely escorting.
