He build a shell gets people to help pop stuff, organises runs to suit himself, when he gets what he wants server changes, has far has i can tell been on at least 4 different servers. in last couple years.
recently built a znm on gilgamesh organised runs which suited himself then broke linkshell & server changed with no notice to anyone.
If he moved to your server be very weary of this before you join any future shell of his or let him join yours.
