Hey @Gurruchaga,
Welcome to the community and thanks for taking the time to post on our forums.
I'm really sorry to hear that you're having issues with spam coming from your account.
I have tried to locate your account via your community profile but have not been able to find your account.
Which page is rejecting your details? Is it the My Virgin Media login screen or the login for your email account?
You can also find more information on how to stop this from happening here.
