These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.
Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.
Can I purchase or sell account interactions (i.e. Twitter followers, retweets or favorites) on Twitter?
No. Twitter strictly prohibits the purchasing and selling of account interactions on our platform. When you purchase followers, retweets and favorites, you are often purchasing bot (fake) or hacked accounts. Any account caught participating in this behavior will be in violation of the Twitter Rules and may be suspended.
If your account is found to have purchased followers, retweets or favorites, your account may be suspended.
If your account is promoting the selling of followers, retweets or favorites, your account may be suspended.
If your account is set up with the sole purpose of selling followers, retweets or favorites, your account may be suspended.
