How to report an account that messaged you?

I got a message from a random account that says the following:

"请帖:男生上分，王者教学。。。女生娱乐，聊天哄睡。。。真心话大冒险等一切游戏服务。。。另有三角洲代肝哈夫币，3×3箱子等。价格优惠，汉子暴力！妹子听话（24h持续接单）微信：q365227525 （可以直播）"

But I dont see any way to report it from the chat box or when I visit their profile. What am I missing??
