Ah, I see. Well I've only been able to dig up one instance where another username popped up, but I also often get reports from Apple and android devices, of which I have none. I also don't have a Wi-Fi connection, which is why this seemed somewhat odd.
Recently I've noticed a few instances where tests on my connection are being made that are linked to a specific username on here. I'm unsure what to make of this and was hoping for some insight. Best regards.
