Are you scared of receiving an infraction?
Not really, no. I think the only time I think I've been scared of them was when I first joined PC, back in '08. I didn't want to get anything against me at all, but then all of a sudden WHAM a warning from BeachBoy in Welcome and BAM an infraction from Amachi for going off topic in the DCC. From then onwards, I realised that the 'scary' part about them was over and though I'm saying I like them, I'm not afraid of them. I think I have like, seven warnings/infractions, lol.
Additionally, do you get a little nervous if you see a PM and you aren't exactly expecting on in your notifications?
Well, to be honest I get a bit of butterflies when I see a pop-up that I'm not expecting. Not because of infractions or anything, though that does go through my mind, but because they're really exciting for me and I love seeing what people have to say or if I got something. Though if it's just some spam member asking me to join his/her forum, it just ruins the moment for me. ;(
