I had the horrible experience recently of having my gmail hacked into and used to send spam. I first noticed when I received a few e-mail responses that said my e-mail couldn't be sent because I had reached my daily limit of 100 e-mails per day. I looked in my sent and found spam about drugstores being sent to my 346 contacts. I started getting responses from people asking why I was sending them that stuff. The horrible thing was, I couldn't answer them to explain because I had reached my e-mail limit!
I checked on google to find out what I'm supposed to do if such a situation arises. It directed me to my "recent activity" and I saw that my account had been logged onto in such places as India and China! I was told to change my password if there was any suspicious activity, so I did it immediately.
After 24 hours my e-mail reset and I was able to send e-mails again. But now I don't know if I should use up my 100 e-mails a day to send e-mails to everyone on my contact list apologizing or if I should just assume my friends would know that it wasn't something I would do. I decided to blog about it.
But guess what....today my blog disappeared. It was taken off line by the spam police. Anyway, I went through this whole password verification thing now and I am hoping to G that everything is over and this will show up.
