Unless there is another snapshot that contains the content for the website (likely for most websites) you should use that website. If the only snapshots available for the site are a 301 then it won't be able to recover the content as there is no content to recover.One question, the website whose data I want has been 301'd. Even in the wayback machine, it doesn't give any info other than connecting me to the 301'ed site. Would your program be able to bring that content and site structure back?
You got some pretty spammy looking posts there mateKeep up the good work
