ok, there's one easy thing to do, you know he's lvl 10, dont flag yourself, if you do, he can kill you as many times as he want it.
Second, if you flagged yourself, the first time you die, just use /stuck to get teleported to the initial area and then relog, he wont be able to get to you in less than 1 minute, enough time that will allow you to ressurect and relog.
Sorry bout my english,
