Pardon my interruption to the flow. What about the threat of search engine penalization for having unnatural looking bunches of new links appearing, particularly for the small timers who have a total of 10 links, suddenly have x10 or x100 the number. Has anyone experienced the down side? (I can't image it too deadly, or it would be used to torpedo the competition)
Instead of the quick turnaround these services promise, I would rather get a trickle spread over a couple of weeks. One model I considered, pay an account balance up front, allowing micro sets of additions to be ordered up periodicly.
