37.228.116.129 spam
Spammail mit unerwünschtem Sexangeboten. Passt auch überhaupt nicht zu meinem Profil. Da ich über Freenet schon gehackt wurde über russische Server, könnte meine E-Mailadresse aus diesen alten Vorfällen stammen. Ich habe vor kurzem eine Warnung von Apple über unerwünschte Aktionen auf meinen Internetaktionen bekommen, die ich zu entfernen versucht habe. Das ist mir wohl auch auf dem E-Mail Postfach von Apple gelungen. Aber auf dem Original Freenet Kanal ist mir das wohl nicht gelungen.
