Re: Scammer
I'll move this to Player Support as more appropriate. However, I should say that the correct place for reporting scammers and troublemakers is the Community Watch. This is no longer found on the Forum, but rather is part of the Playerdex. You'll find it by clicking the "
Community Watch" link after logging in to the Playerdex. (Bug Reports and the Suggestion Box are also part of the Playerdex, as they all run off the same system, which was introduced in the Playerdex update that launched over a year ago - however Suggestions may still be posted on the Forum as well).
As for your other complaint, if you are having trouble logging into the Forum with your in-game username and password, but you can get in via the Playerdex - it may help to change your password again, as sometimes (such as after a password reset), the passwords become de-synced from the Forum and you need to change it twice to get it to work.
