Please, let me know what u guys think?

Today i been enjoying made some updates of my blog's design till i decided to check my gmail and one email from Linda (http://lindasnailart.blogspot.com/) caught my interest. I dont know her but she told me that my own posts  here and her posts from her own blog appear on http://topnailart.blogspot.com/ Do anyone know about this blog? This blog is definitely copied my posts and definitely same! It seems like every posts i made here, will be copied automatically to their blog. I really have no idea how could this happen? Do anyone know anything about this blog (http://topnailart.blogspot.com/) and could tell me why my posts definitely appear on there?

These are proofs that they appearing my own posts :

The first picture is the post with title "Back to Nail" that i wrote on November and it appear on that blog (http://topnailart.blogspot.com/)
The second picture is the post with title 50% of Flower that i wrote on December and it appear on there as well. And any other my posts appear on there. I really dont know how could this happen and im bit dissapointed they did this to me. I know i dont write any policy yet of "onmynail" blog because i still cant write right well english for it but i think none would like if someone definitely post something real same from somewhere's blog without asking permission at all.

Well, i thank to Linda for informed me this and i might never know if she didnt email me.
