This dude always using the same chat pattern to scam;

In first few week server opening, MYSG RO community have been alerting by this scammer's tactic, thanks to few of his victims by posting the chat evidence in the Facebook group.

However, despite several reports had been made to server management, this scammer still roaming free and continuing his scamming activity every fucking day.

Afterward, the result of being a non-worthy criminal freely roaming in the server, SeiSeiLap instantly become a well-known figure after countless reports by community spotting SeiSeiLap and posting in-game screenshots in Facebook Group and treats as a meme and joke.
