I was playing total drama on roblox and ppl kept saying we were teaming

Me and my sister were trying to play total drama and since were sisters we obv have each other friended on roblox. So when they said we were teaming i explained we were sisters and they still voted us off. We have been trying to play for 2 hours but they keep saying were teaming. My sister is 6 years old why would i team with a 6 year old. It just bugged me and i had to say something about it lol
