I got a message like as well a while that saying 'come' or something like that on it I think.
I have a picture somewhere, I'll dig it out!
Here we go:
I believe i sent that to you, i like to only have people i know on my friends list, but i decided to ask some other ppl to be my friend to invite them to play cute or boot. I sent them all messages saying 'Come Play', but then deleting them imediatly after bc i forgot that u have to be friend to follow, since i was no longer your friend, it resulted as an unknown.
