Actually I suppose it isn't new, but it is new to me.
It's essentially a different way of presenting an old trick that I nearly fell for it, and I'm blogging it to prevent you falling for it.
Last week I was phoned by a lassie with a very pleasant Scots accent - somewhere in the Central belt, I think, but not Glasgow or Edinburgh.
She said she was conducting a survey on behalf of Genealogy UK magazine to find out about the family historian audience in the UK.
That's believable, though I hadn't heard of the title, there are probably lots of magazines I don't know.
She said she would ask me several questions and she asked me to indicate the answers by pressing numbers on my telephone so that they could be captured automatically and stored in a database.
The first question was "How long have you been researching your family history ?"
0 for not yet started
1 for less than 1 year
2 for 1 to 3 years
3 for 3 to 5 years
4 for 5 to 10 years
5 for more than 10 years
I was just about to press 5, when it occurred to me that whatever number I pressed, I might be connected to a premium rate line, so I just put down the phone.
The BT 1471 service told me "We do not have the caller's number to return", which I think means that the call originated outside the UK.
I wouldn't have blogged this at all, had it not been a genealogical pretence, however, a friend who has not researched their family history, also had a similar call.
I've since discovered that there is no Genealogy UK magazine.
Have you had such a call ?
