I'm running a Kickstarter, and maybe people who have done this before already know this, but apparently this gets you a lot of spam. Since starting it three days ago I've gotten eight different message offering to help me get my campaign funded, via Kickstarter's own messaging system.

Since I haven't gotten any legitimate messages, and these all look pretty aggressively commercial, what keeps Kickstarter from blocking them?

(On the other hand, since creators are notorious for using Kickstarter to spam their friends about supporting their projects, maybe this is just a thoughtful way to restore balance in the world?)

Here are snippets from the messages:
