I've never experienced Mori here at AT, but someone using that handle (I have to assume it's the same person) invaded Sharky's BBS when it was on Delphi last year. Very bad english, basically "american's were suckling" to his penis and so on and so fourth and were generally interspersed with "ahaha ahahahaha ahahahahahaahah!!!!!!" and ended with "Satelism!!!!!!"
Sorry to hear you had to endure him here. LOL.
