Yea, after seeing the replies here, I'm thinking this is a definite no (well, 99.99% sure anyway).
OP, assuming your plugin and the 'service' is legitimate, there is absolutely no reason to approach any admin via PM when they specifically ask for details in the public side of the forum and do not say 'yes, PM me'. That raises a rather large red flag, especially if said 'service' is legitimate. I also did note that the main web site says nothing about monetizing the URL's posted, but yet the description you gave did?
If this was something that we really wanted to do, we would have already written up a script/plugin that would do it. Thanks, but no thanks.
