I sent out a (friendly, helpful) link request recently and got a reply back that 'my link is on page x which they are waiting for Google to index'.
This read oddly for the industry (small - hobbyist level), so I did a doubletake and realised that a) the response was from the website owner's seo company and b) page X wasn't linked from anywhere on the site.
Waiting for Google to index it indeed!
I didn't dignify them with a response - it was easier to get the bad taste out of my mouth that way.
So 'amateurishness' can go both ways...
