The forum private messages and the in-game emails are the same system. When you view the messages in game, the reader window has a "Report Spam" button at the bottom. This will both add them to your ignore list automatically, and flag them internally as a spammer. If enough people flag them as a spammer(in either chat or mail) they will automatically be banned from using chat and email, and flagged so that GMs will investigate them and possibly ban them from the game.
That seems to explain why I didn't receive any spam messages until I posted on the forum...
Does that correspond with everyone else? Did everyone who received this spam also post on the forum before it started?
I'll have to look into the /whitelist option. Is there a /blacklist one too? So I can blacklist by Subject for example, as for now all my spams have the exact same subject: 'Cheap_STO_Energy'.
I too would like to see the ability to report PMs via the forum as spam. Especially at the moment with a queue system being used. I don't want to spend hours queuing to get into the game then wasting play time reporting spam.
If you want players to report spam so that action may be taken, allow it to be done from the forum as well, please.
