Those influence peddlers should be strung up and boiled in oil!!! Well, at least permanently delete their accounts, and ban their credit card owner from ever sighning up again.
As far as the ingame e-mails go, a spam button would go a long way. That way we would only need to highlight the offending e-mail and click the spam button. Being able to select multiple e-mails would be even better.
This way, there will be no errors in reporting a spammer who has one of the long nonsensical names that have used uppercase i's to stand for lowercase L's, and such.
Peace out
