Avoid SCAMS

I was searching blogs and I found a lot of blogs that advertising sites such as PTCs.I know that most of PTCs are SCAMS .It was great that I saw most of blog's post were wrote about non SCAMS .This sounds so good because the writers tried to keep blogs reliable.I think on internet the most reliable sources are blogs but some them was wrote about SCAM sites.I hope they change their posts soon before anybody else use those sites.
