For example, a girls skirt being sold as "bought for my daughter but she didn't like it as she's a tomboy, so sadly selling".....then when I look at her other listings she has the same skirt in sizes aged 2-9, all individual listings!
Not a biggie, and not illegal but it does make me chuckle. Do they think people don't look at other listings?
I mean, I suppose she could have fallen in love with said skirt and bought it in 8 different sizes for her dd, but really?! 
I think it just makes me a bit wary about what else they may 'lie' about...
