TL;DR: impossible to delete old skype accounts without knowing EVERYTHING about it. I have like 3 old skype accounts which shows up with my name which I can't access due to me not having the email addresses anymore nor do I remember the passwords, so it is a pain when people try to add me on skype and I contacted them and asked if they could delete my old accounts since I can't access them and they said that is not possible since I don't remember all the security questions and answers, wouldn't even give me the questions so I could have a chance at answering them.. Edit: added TL;DR
