Plaz is like an STD, and Blockland got it.
However, the symptoms don't come too often. Maybe every 2 or 3 months.
It is a very tricky disease, and could slip away from any suspicion, mostly because of Blockland's overbandwagoning causing misdirection. Plaz could be anyone. Azjherben. Goobler. Or the loving Console that single handedly hacked Badspot. You could even know it in real life without knowing. Your best friend. Your brother. Your gym teacher. Or even your mother!
