Maybe you got hacked that's why you couldn't login.
Check if your mog station has an additional char even if they could have abused your main.

For now, if you are still able to, I would change the password (email's too), attach a software token and contact SE. Tell them you couldn't login and that then you got suspended and that if it was for RMT activity then you were probably hacked. Just to be sure scan your PC with an antivirus/malware before changing password.

These hackers are hacking so many people to spam their shitty service and people still support them
