You said it doesn't take a genius to work it out but you haven't worked it out. It's opaque other than that we know it's a flag that can be manually set on the user without their knowledge

>>bowsam+(OP)
I worked out that I had been flagged. I was not saying that dang replying was the mechanism, you are just (intentionally?) misinterpreting what I am saying. That dang replies to you is an indicator that he has flagged you.

Not going to keep replying, as I suspect that a conversation between two people flagged in this manner is one of the likeliest to turn flame-y :)
