Let's have a look at it:
Era PC - sold items and staff positions for USD (admit doing so, he did), reset and banned a lot of people without any reason, just out of boredom/disliking them (See previous () )
Kingdoms - banned people w/o warnings and reset their accounts without any legit reason nor previous warning, created NPCs just to harass people
UN - basically #2 and so on, which I am not interested to go into detail ATM, maybe tommorow when my brain is working properly again (check my spelling/grammar and you see how bad it is).
He's probably done some other issues or will do soon on other servers aswell, can't recall right now. However, despite his somewhat "good" development-skill (he did not know how to link levels ago a year, lol..) his behaviour is nowhere near being mature/acting like an adult, he isn't capable of being in hold of ANY high staff-position. Nowhere. No server should have him hired as an high tier. Having him as a PWA just reflects Graals 'marketing strategy' (if you can call it that way, which is ridicolous aswell). Nothing to say about Robby, since this thread's about Carl.
It's sad to see how much Carl destroyed UN. Anyone saying Ramza or the staff is to blame, doesn't know background stories. I'd happily explain it if someones asks me to do so. Yet another stupid and useless move of the PWA to bring Graal PC one step closer to its final death. Sad to see it going this way.
Again, me brain no hables inglish, soz.
