I think that japaneise version of the games and special cracks put on the pso game can make you able to pk...

As for pkers/stealers/ect... i havn't got online yet, but i allerdy experienced that on other games. This is SOOOOO fun to loose all our items that took out ages to find ! </sarcasm> No really. You guys should stop that. All it does is making people hate you.
