I just saw that someone created a very similar site to mine. Same topics, same navigation, same headlines, same affiliate links and even the WP theme is same. Lolz.
I did run it through copyscape.com and the homepage is 5% same as mine, but the length and everything else is same. It seems like he only changed the wording a bit so it wouldn't count as duplicate.
Should I do something? Or is it legal?
