Someone gave an example of searching for "IBM Leapfrog" and getting numerous Pinterest results.

I tried that search and only got one Pinterest result in the top 10.

I had no problem getting the text and images using a text-only browser. Could Javascript be the enabler for this Pinterest/Google annoyance?

Here is a quick little script to dump all the text from a Pinterest page; note how much is devoted to SEO and ads. .jpg URLs are wrapped in anchor tags for convenience.

    curl https://www.pinterest.com/pin/509469776569152019/ \
    |exec tr '<' '\12' \
    |exec sed 's/, \"/\
    \"/g;s/{/\
    /g;s/}/\
    /g;s/\[/\
    /g;s/\]/\
    /g;/\":/!d' \
    |exec sed '/ \"/!d;2s/^/<pre>/;
    /\.jpg\"/{s/\"/<\/pre><a href=\"/3;
    s/\"/\" style=margin:40px >viewjpg<\/a><pre>/4;};
    $s/$/<\/pre>/' > 1.htm ;

    firefox file:///1.htm ;

With respect to LinkedIn, here is an amusing experiment to test the theory that your time means nothing to some web developers: Try signing up for a temporary account with a 10-minute email address from 10minutemail.com. LinkedIn will not inform you that this is an unacceptable email address. LinkedIn will proceed to show you Google ReCaptchas for at least 10 minutes, and perhaps longer.
