But the situation you described is such a rare occurrence. I've been playing for nearly a year and have not come across anything like this before.
I understand you're anxious, but you have no issue in explaining yourself on the forums so what's stopping you from saying something when you're in that situation? There's nothing wrong with being anxious but realistically, you're talking to people online and if anyone reacts negatively towards you; just blacklist them - you have tools at your fingertips for your own comfort.
