ID: 155 went on Tails server as "snot" then... "INVA snot" joined and we knew it was the real snot, so I kicked "snot" . Later ID 155 rejoined as "Mucus" and said "Do you know who you just kicked??? That was the real snot" then "INVA snot" said "Im the snot :D" so we kicked Mucus, then the same ID rejoins as "Destruction" and tells us that it was the real snot. We perma-banned him. Later observations said it was Terror who was doing this. Just to let you know because I saw "snot" in other servers too.
Recap:
INVA Snot = Real
Snot, Mucus, Destrucion = Terror
