People sometimes forget that freedom of speech doesn't necessarily mean that everyone has to hear or read what everyone says. People should also have the freedom to configure their social experiences however they want. This includes muting or not seeing anything that I don't want to see. The spammer wins because they can spam the network. I win because I have them filtered out and don't see things I don't want to see. It's a win/win situation if everyone is given the freedom to do whatever they please here.
