Good work, Cerasus, the IP addresses might match up to one individual. All of the spam that I've seen this last week or so has shared common themes. But...IP addresses might not be enough. This is why I'm suggesting an automated solution based upon repeat tendencies. Another option would be that the site, in circumstances of heavy spamming, temporarily empowers 'fire wardens', with the proviso that they may only delete spam, and spammers.
