Graalians - Why is scamming legal(in my opinion)?

Chaotic put it perfectly.
Its not encouraged by Era's staff team.

It is stated as "Legal" because it cannot be stated as "illegal".
If there's a stamp that says "illegal", people expect justice.
As Era GP back in 2006, one of the most frequent inquiries I received was "help I've been scammed!"

All I could do was go through trade logs, item drop logs, and money logs that stated they dropped the item without receiving collateral. For all we know, you lended your item to a friend and you got mad at him, and this is your way of getting back.

While we're genuinely sorry for any loss, no action can be taken because there is no solid evidence that backs your accusation. Take it as a life lesson about society; a lesson that is applicable outside the world of GraalOnline.

Scammers are shameless people taking advantage of naive people.
