I'd suggest that exploits for Facebook wouldn't actually sell that well on the black market. There's only one install of Facebook in the world and it's controlled centrally so can be patched at any time. It's not like an exploit for Windows which can go unpatched for months if people don't install an update - those are worth money because there's a real use case. With a Facebook exploit you'd get a few hours of spamming at best before it's patched and all the crap you posted is deleted - that's probably not worth the money.
