My yahoo email account was working last friday, i logged out as usual, tried to log in about 4 hrs later and i couldnt log in with my password. I tried to get my details sent to my alternate email, but this is no longer active and i didnt realise it was linked to my yahoo still. I have contacted yahoo, after a few automated responses, they have asked for a copy of my passport and other details to get my account restored. I have faxed all these details of to them and now I have had no response. Nothing. I have even emailed just to ask if they have recieved the details but not even a reply. In the meantime im sitting here wondering what important details are actually in my email account that would be hacker type person has got hold of and what damage they are doing to me with my details. Yahoo are you actually going to respond to me? Are you going to restore my account? Iv sent you a copy of my passport, what else would you possibly need?

I don't know whether to be angry or resigned! I had a similar problem Dec 05/Jan 06 and it took a couple of months to get it all sorted. Postings were made in my name on two chat groups I didn't belong to and emails from one chat group I hadn't joined kept coming via a linked 'forwarding only' site on my web page. Yahoo were very slow in coming to any help (I forwarded all the unwanted email to yahoo dozens a day). However in my case the object was malicious rather than criminal and there wasn't anything sensitive in the linked website. I suppose the moral (in my case) was don't trust to yahoo's security and keep a distance between yahoo and anything sensitive.
Yahoo were slow, reluctant and disbelieving but I guess they got there in the end. I had to change passwords on everything, especially the web host and linked site but it still took me months to feel safe. Yours sounds much more serious - I hope you/they manage to sort it quickly!
