They are spamming my e-mail -.- (because of subscription to threads) Seriously, is there no way to stop them?!
I had my main email account hacked by someone in china somewhere like 5 months ago and when I took it back I had a spam of failed delivery notifications and read some and they were all selling gold power leveling and other kinds of creepy stuff. Under my freaking name! 2 weeks later i got another hack and then the account became suspended for good... Oh well, at least it's not me you're recieving those mails from...
Wait, do you get direct selling mails because of your subscription here (can't imagine this but I'm not too well versed in IT) or do you get notifications of bumps by ads? If the latter then you should change in your settings that you do not want to subscribe to threads you reply to or that you don't want e-mail notifications of replies. Both come at a cost but there's nothing we can do to prevent this.
