Thanks for this guide! Any tips on what it means when I am surrounded by team diggers (on team mode) and they are bashing into me constantly?

On agar.io this often means they want more mass so you can share it. It's not possible to do this on digdig so I don't know what they want. I am bigger when it happens and they are much smaller but they follow me and constantly hit me. It's really annoying. I thought they were just with me for protection (due to their size) but it's happened often and I don't know what it means. What do they want?
