It's quite unusual for post that isn't hugely obviously spammy to get this many downvotes, but as you can easily observe this particular thread is seeing a huge amount of traffic. I'm afraid I don't have a huge amount of sympathy for getting burnt while playing with fire.

The only ways I know of to drop 100 reputation quickly are to (1) offer a bounty, which you didn't do, or (2) have one of your posts deleted as spam/offensive. I don't see any questions that have been deleted that way recently, but it's harder to track down answers. If one of your unpopular answers was recently locked and deleted by the community user, this is what happened. I'll have to dig into the database to see if this guess is correct, and to see if there's any funny business with how people are flagging things as spam/offensive.
