i think your friend gets ebay call when he logs from his work,especially if the workplace
is more than 25 miles away from where he originally open the ebay account,and also the IP address is from his home is provided from xxxxx internet company and the IP address from his work is provided from another internet company different than his home,.
i get couple calls when i was a newbie on all this and i now realize is because i used to logs my accounts from my workplace 45 miles away from my home.
Hope that help you understand a little bit  |
