We started the TIDE project with Snowshoe Spam domain detection. But what is Snowshoe Spam? In Snowshoe Spam the spammer tries to spread the sending load over numerous hosts, and thus reducing the amount of spam each hosts sends. This makes each host separate hard to detect. It means that the spammer is less likely to end up on spam reputation lists (blacklists) and is therefore able to continue spamming for longer.
