If a site gets 0-1000 hits a day and has 300 back-links then I think google will
consider the site nothing more than spamming to get SE rank.
Which is exactly what the site is doing.

So what you paid for the link; it's still spam because the link would never
be on that page pointing back to you if you hadn't "made" it appear yourself.

"Building back-links" is in fact spam.
