i know that level 1 admins arenot supposed to have as many powers as higher level admins but a basic ban command (at least for 30 min or sth like that) should be possible as level 1 admin
the resaon for this: today we had a hacker in the server and only a level 1 admin was there and he couldnt ban when he rejoined after kick
as vban cant be used while an admin is in the server, the admin had to leave in order to enable vban for another member
so id say give level 1 admins the power to ban
