Did you think the "no two-box" rule was taken lightly?
Our Guide's don't just "show up" without observing first. Eunomia was likely watching for quite some time before revealing herself to you. She has a lot of experience dealing with two-boxing and has basically written the book on two-box procedure here on Project 1999.
Code:
SELECT * FROM `pc_login` where accid in (*ACCID'S REDACTED*) order by ts desc limit 0,5000
You had two clients open on one PC. As you can see above, I checked the login table in case an error was made. Eunomia did exactly what she was supposed to do and suspended you.
If you choose to play here in the future, please follow the rules. Also, if you'd like to protest a ban/suspension, use the petition forum. Making a post in server chat usually just makes your situation worse.
