This sadly happens a lot. All I can say is its clear the cakes are not hers, she hasn’t rewatermarked them or cropped out the original watermark… Or even added a watermark to some of those without one. I saw worse on that site that stole Rosie Cake-Diva’s cake, they cropped her name off and wrote theirs on, plus they’re from a country where there are clear copyright laws and they were in no doubt they were doing something wrong and illegal- strange as it sounds this lady may not realise she’s done anything wrong because she hasn’t claimed she made the cakes. But I agree she shouldn’t put images up from others without permission. I hope you get the result you want xx
