This appears to be the second incident in a short period of time of someone trying to get players banned by having them take a look at a "safe" account for whatever cruel intentions there may be. Because of this, I cannot stress this enough...
No matter how curious you are,
No matter what someone promises you as a reward,
No matter how difficult the game may seem to you right now,
NEVER LOG INTO AN ACCOUNT THAT A COMPLETE STRANGER GIVES YOU ACCESS TO
Spread the word, make others more aware of the dangers of simply logging into an account that does not belong to them.
