Targeted ads in A mish mash of entries

Targeted ads both annoy and scare me. Presumably from the depths of a clever website that somehow got me to input my age, I'm getting ad after ad HERE ON PROSEBOX about services for (choose here)

• Old Age Pensioners
• Senior Citizens
• Life-experienced
• Mature People
• Seasoned Citizens
• Grumpy Old Women (I guess I must have input my gender somewhere too)

Saga insurance, which I would never use because they're consistently more expensive than mainstream alternatives. For walk-in showers and showers that have seats and hygiene aids (what the hell are they?). For fifty plus clothes (don't they know that 60 is the new 40?). And so on.

Recently I had to do some research for work on drug and alcohol problems and the relationship to mental health. I used my own computer because 1) it's faster than my work laptop and 2) the work server throws up its hands in horror if asked to search anything like "alcohol" or "drugs" and refuses to open the page. The ads I'm now getting are eye-opening..... amazing - although these ones are not on Prosebox. Veiled suggestions for a chemically enhanced sex life, cheap alcohol, how to avoid showing positive on a breath test and heaven knows what else (the ones I'm scared to even look at never mind open).

So why are the ads on Prosebox limited to the insulting ones (yes, I AM in denial about being old, so it can't be true, so they're insulting), and the really dodgy ones only appear elsewhere? Bloody clever, aren't they?
