Currently, there is no cost associated with Google Base and yes, with any free product there is a large potential for spam abuse. If you take a look at Google Base overall though, it seems that they are doing a fairly good job at keeping spam off the system. There will never be a way to keep this free service 100% spam free, but rather more about keeping spam levels in check. I would assume that as the service becomes increasingly popular, Google will dedicate more and more resources towards the monitoring of the system.
