It's just like any other push-in-your-face advertising
Well, if I'm out and about and some stupid twunt from the bottom of the marketing foodchain tries to push halfbrained advertising in my direction, I offer to read it and act on it as I see fit for a fee of £50 per item. That usually puts the idiot off and, assuming they have enough cranial capability to spare for memory, they might just remember to avoid me in the future.
Quite honestly, I don't see any difference between some twit trying to stop me in the street and tell me about double glazing, and the same undesirable trying to send it to my bluetooth.
Yes, I could always set by phone to non-discoverable but, there again, I don't go out wearing ear defenders and a blindfold just so I can't be assailed by marketing muppets.
On that basis, here's the pitch to anyone trying to bluejack me without an invitation, in order to send me marketing malwords.
I'll go around, without a blindfold, ear defenders and with my bluetooth set to discoverable, if I so choose. If you want to send me unsolicited marketing material, I'll be pleased to receive it, review it and act on it as I, in my sole opinion, see fit, for a fee of £50 per item received. Any attempt at sending me such material will be taken as your unconditional and irrevocable acceptance of my offer.
If you don't like my terms, just don't bother sending me anything. It's as simple as that.
