How do I find someone else who has Yahoo?

i work for a public school Someone is using my email to send porn to the people i have on my email list please help me find out who this is

i've emailed yahoo several times with no reply. only that i need to know my current password to change or cancel my account. does yahoo have a phone number for customer care. this a serious offense.

someone gave me their yahoo id and told me to hit them up but i typed in their id but it didnt take me to their profile.

not really much else to say I got a mail and am trying to find more about the sender

someone has changed my yahoo password without me knowing it i tried to log on and i couldnt i realized my password had been changed how do I find out who

thay are checking my yahoo mail with a computer that thay stold and using my id . etc

Someone took my info off of myspace then created an email address in yahoo. We need to find this person and make them stop. I would like to know who it was, since they are sending out bad material to close people in my life.

I have a yahoo account myself and someone with a fake name is emailing me threatening messages. I think it is someone that i work with. How can i trace the email address to the ISP# from the computer it came from?

If someone uses the email address, "ilikeclowns@yahoo.com" for example, how do you find their real name?
