Could this be "The Clone Codes"?

A search suggests that the story contains numerous references to clones (duh), clone rights, virtual avatars of various famous abolitionists and a benevolent alien species called "The O":

In the year 2170 an underground abolitionist movement fights for the freedom of cyborgs and clones, who are treated no better than slaves

The Cyborg Wars are over and Earth has peacefully prospered for more than one hundred years. Yet sometimes history must repeat itself until humanity learns from its mistakes. In the year 2170, despite technological and political advances, cyborgs and clones are treated no better than slaves, and an underground abolitionist movement is fighting for freedom. Thirteen-year-old Leanna's entire life is thrown into chaos when The World Federation of Nations discovers her mom is part of the radical Liberty Bell Movement.

...

With the help of some virtual “Custodians” (Ben Franklin & Eleanor Roosevelt & others), Leanna learns some harsh truths about the world she lives in.

...

The entire thing with the O seemed to have been pulled from a cheesy scifi movie and made the plot way to complex.
