We have email spam and IM spam. Today I received a spam text message on my mobile phone (either Sprint sold my number or the spammers haven’t even bothered to harvest numbers, simply sending them out in numerical order because it’s so inexpensive). Oh joy. Next I predict – and I probably shouldn’t say this out loud – spam in the comments section of blogs. Essentially anything we use to communicate, unless it’s a private network, is vulnerable. We’ll have to start anticipating this and designing protection in at the beginning, but I wonder if that’s even possible.
