That's ridiculous, because they are definitely a way to earn money, and in a lot of countries it can be a substantial amount. Dirt poor people who can't write English know this and flock here in droves and thereby pollute the water supply. What we need is some big guns doing border security--and things like smas help.
When you view them as a source of income rather than a reward for contributing to the community, you are going to abuse it. To gain as much as possible, you are going to farm hundreds of accounts to earn about less than $300 per month. If you're in some third world country, they probably don't have internet at all due to their high cost. Its way more effective to work at a local macdonalds or something. Its not about how they cannot speak English, its about how they don't put effort in any of their posts.
I'm not saying SMAS isn't effective. It is, but how are you going to regulate the spams from the alt coin section etc?
