Yahoo Messenger is it safe?

I think it's either you were not able to log out from the messenger that's why other people had access to it, OR, your email was simply hacked. My techie friend would advise for you to change your password first. If it still spreads spam messages, I guess start thinking of having a new email address soon. In the meantime, make sure that when you use messenger, you log out completely and tell your friends to monitor it as well.

Me I have experienced this also, I notice that many chat rooms have an adult directory. When you enter on that room, someone will say "high do want 2 see me on cam"? when you replied to them they would invite or use your user name to attract other users. Even if you logged in on another day your inbox is full of adult ladies inviting you to their websites. From that day I usually don't use the messenger but I use paltalk.

hello
yahoo have a lot of Bugs and they do them bests to stop the spam bots, unfortunely yahoo is a great service at everything and i like it a lot, i use it also since i had 14 years old and my yahoo mail still working, the thing is that You have to change your password every 1 month, like that you are safe;)

Your email used to spam is not a new thing, because the spamers use a lot of emails which they can find easily with google and msn search engines, they use a randome emails to send them stuffs through a Mass mailers and so.

just do what i told you, change your password, do some restrection and privacy at your account oiption and all will be fine;)

all messenger's are safe ... but MSN messenger is most safer than these all ...
