I don't rank prospects. I don't do anything really. I aggregate. That's what I do. So I aggregated the prospect rankings for 4 expert sites. Baseball America, MLB Pipeline, FanGraphs and Baseball Prospectus. In the case of BA and MLB, they rank top 30s per team as well as top 100 MLB. The other 2 rank only for MLB top 100 or 101 in BP's case. The result is a more interesting view of prospect rankings. I've been capturing the rankings since BA started ranking in the 1990s.

In addition to the prospects section, you can also view a prospects history on their player page under the PROSPECTS link in the black bar at the top of the page.

There is nothing PREMIUM about Prospects on the site. Its available to everyone. But if you wanted a dump of my historical prospects data, you could get it at a discount in the data store if you happened to have the PREMIUM account. Just saying...
