Be Careful What You Click On!

You've clicked on nuts and new mown hay,
I'll take the cello and some good red clay.
But everybody's done it often: you have, so have I --
alighted on a website when only surfing by --
and it's asking in all innocence
for what might be your preference... on film types now... do you go for high suspense?
or are you more for comedy?
And on another matter,do you retain your Teddy?

It's just a bit of fun, saying if you like or hate 'em --
and then how high or low you rate 'em...
Would you prefer a dog or cat?
What harm is there in that?
But behind them lurks a profiler
with algorithms of a complex kind
who wants a profile for... er...
all sorts of people come to mind.
Traders without number who want to target you.
(You've given more away to them than you had wanted to.)
Authoritarian regimes, who see an odds-on bet,
have their own algorithms set
to winkle out your politics
and then apply their fix.

Is The Godfather a favourite? and also curly fries?
That tells them straight away -- I promise you, no lies --
that you are blessed with high intelligence!
Steam trains and fish though, here I dread to say
what that could tell about your sexual preference!
Big Momma's House and milk shakes... together these two lay
you open to a drugs charge. But perhaps you ride
a Harley-Davidson? If so, I can confide
you are in academic eyes the blue eyed one with brains.
Me? I've not got past the trains?
