In yahoo groups how do email addresses work?

Question

If a person has a lot of email addresses, say from here, there and everywhere else over the years, can they be a member of a group or sign into a group with all of them? If they do that can they even never use an email address of theirs again, but just stay signed in. Can they just be signed in under that name for as long as they have it and therefor inflate the group member numbers? What if they let that account go and get another and are signed into a group under that email address if the email address does not exist anymore could that email address still be used in a group? Can a person actually use someoones identity to get email addresses without them even knowing it? How does all of that work without that person knowing it? Is there any way to stop that? So that a group is as legitimate as it looks to be?

Answer 1

A person can have a lot of e-mail addresses associated with Yahoo Groups in general.  But each person/member of a Group must pick only one of these addresses for use in the Group.  So it won't inflate the Group member numbers.

Also, to have an e-mail address associated with Yahoo Groups, a person must first verify it.  This must be done by clicking on a special link in a message sent to that e-mail address.  So that's how Yahoo prevents a person in Groups from associating other people's e-mail addresses with that person's Groups - because the person won't be able to log in to other people's e-mail addresses to click on the link in that message.

EDIT : Yes, Yahoo has a way to figure out if an e-mail address is bouncing or not.  Any time it sends a message to that e-mail address (whether it's the message sent for verification of that address or a message from a Group), if the message gets returned with an error, then the e-mail address is considered to be bouncing.  If the messaage is not returned, then it isn't considered to be bouncing.

Answer 2

Yahoo Accounts/ e-mails are each to their own, each would need to sign up membership for each group. if they sign into one account that is not a member of a group, they wont gain access to the group and will have to join. e-mail addresses other than yahoo mail can be used with any Yahoo Account.

e-mail and Yahoo Accounts can be phished. if that happened the person would know cuz the phisher changes the pass word pronto. people who have strong passwords and don't fall for pretend 'official' mail wont get scammed.
