Go to the group page you want to spam when running this.
Inspect Element->Console and copy and paste the code.
Wait time can be adjusted and the bot will attempt to send messages super fast, but it's good to keep the time high or ROBLOX will detect flooding.

You can change the group number to the group you are recruiting for so that it doesn't send the message to people in that group.

I would be delighted if you were to join us and participate in the group as much as possible. We are a fun and immersive clan, we do not just have training's and raids constantly, instead, the Council and I make the group as entertaining as we can. Do consider joining Frostium Legion if you have not already, it would be greatly appreciated. \n\nGroup Link: http://www.roblox.com/My/Groups.aspx?gid=1019757',
