I erm... Yeah.
On the one hand people who make false accusations perhaps shouldn't be allowed to get away with it, as many lives have been ruined this way and the accuser gets off scot free.
... But wouldn't it be more acceptable to wait until you're found innocent, or the case has been thrown out for lack of evidence before doing this? Now it looks less like a cause for justice and more like a deliberate attempt to smear the reputation of the accuser.
