- Regarding the webchat thing it's probably software on a certain server that was used to create an account on that server. How that contact appeared in gmail chat I have no idea. At this point I'm not really sure how contacts are added to google chat because I haven't used it for like several years. I think it's enough when you chat with someone or send them an email, and it gets added automatically.
- As far as I understand it nicknames and usernames are separate things. Although I've noticed few of the jabber clients I've tried will actually use the nickname... in most cases they will simply display the jabber address (i.e. firstname.lastname@example.org
) instead. Not sure this is due to the client or the server software not supporting XMPP nicknames
, but a google account of my colleague does not display my jabber nickname properly.
- As I said I am unsure how those contacts were added. If the server on their side supports email, it is possible that somebody simply replied to that email, and the contact got added. The best way to avoid spam is not to post your email in public places. Although that's only a partial solution. I've had this challmate of mine back in highschool. She was like the happy person in class and would send greets and flowers to all people in her email address box. Not to complain about her cheerfulness, but this is an excellent way of how spammers get email addresses. Her emails contained the addresses of everybody in her address book.
- I haven't seen them popup for no reason. At least not those of people I haven't talked to.
It's probably just some spam thing. Delete those accounts and see, if they appear again. If they do then it's possible your son is chatting with them. Just teach your son about dangers on the internet. When I was his age I wasn't being careful either and I posted my real name almost everywhere. Lucky me, I had no digital camera at the time or else I would have uploaded pictures as well.
