Hi guys! I'm thinking about churm and burn method on my money site (hacks niches). I've got 1 year old domain and 50% of hacks are in top 20 on google. I want to buy a 2 years old domain with 185k backlinks and make 301 redirect to my site. Is any risk to penalty from google? I get big boost to my site for a while or for one month for example? If I my boost will go down, can I make redirect to another site and my site will be at normal place or on the bottom of google?
