One tiny username changing side effect

I got a message from a user today. He was asking to continue a game we had. I didn’t recognize the name so I went to search for that username. There was none. So I do not know who messaged me.
This becomes problematic if someone starts to troll with it.

generic answers are the best and sometimes even totally topic related, or maybe not who knows

btw. i hear shinkenjoe is only playing *** right now, so he is basically offering free rating points if someone needs them

Thanks.

I asked this reply for forums testing purposes. There was no magic blinking this time :frowning:

what does this mean?
