You can add ShieldyBot. It asks new users to perform a set of actions within a specified period. You'll have to set the bot as an admin, and the bot will take care of kicking out those spammers. Source: about 2 years ago
You can just invite ShieldyBot to your group and give it Admin access. That's pretty much it. It's a pretty comprehensive bot. If you're worried about the public infrastructure you can just clone the repo hosted on Github and run it locally on your server. You just have to register it with The Bot Father.
