I had a bit of a shock the other day. I opened my Hotmail account, which I only use for certain things, such as online ordering, etc, and there was a message from T!! I had used that account to contact her in 2006, following my discovery of an email from her in K's account, so I presume I must still be in her contact list.
It was in Polish, so I ran it through an online translator and it turned out to be an invitation to be her friend on a social networking site that she's just joined (she's obviously on the lookout for her next victim!). She must have clicked to send an invitation to all her contacts without realising that it would come to me.
I must admit I went into a bit of a panic at first. K was quite dumbfounded and doubted that she would do it on purpose (we didn't know what it was all about at that time). I was going to ignore it, but once I discovered its meaning, I decided that I did not want these random emails turning up every now and again, every time she hits a button to mail all her contacts, so I emailed her a polite 'take-me-off-your-contact-list' message with an instruction that I never want to receive any communication from her again. I haven't had a reply so far.
