No, it doesn't seem rather large.

The man made a fortune destroying the reputations of some people, and he did so by (provably) intentionally lying about them, without their consent and with nothing paid to them. They deserve every peny of that - he stole their reputations and as with all theft, reparations are logical.

In addition he grew his following with those lies, and that following will continue to give him money. This is the interest and dividends of those lies.... it's the result of him investing the reputatoins he destroyed. Since you can't sell a following, but it's still a profit generating asset, it's fair to make Jones turn over those dividends. This ensures that he'll be turning over those dividends for a long time.

Finally there's a punative component - making sure he doesn't continue to maliciously destroy reputations for profit. It's a good idea to make sure such a pile of shit thinks twice about he tells more lies to the morons and trash that follow him.
