Is it legal to use other people's photos online in order to get free stuff?

[Ben]

Basically I saw an adult girl on twitter who only has about 500 followers post about 10 photos showing full naked breasts and full nudes but with her vagina hidden by her hands or legs. She posted an amazon wishlist with various priced items and within an hour or so she had over £80 worth of stuff bought for her. I want this but being a male this isn't possible for obvious reasons, so would it be legal to find a girl posting pics anonymously online for free and use them on an alias twitter account as if they are my own in order to get people to buy me stuff via amazon wish lists? However as a future tax advisor (hopefully) a conviction for fraud wouldn't do me any favours so thought I'd ask. Just so unfair females can get stuff bought for them by men everywhere they go, so much for equal rights.
