Difficult one to solve, is Bluetooth marketing Spamming? I’m sure Armando doesn’t want to be called a Spammer, but does the general public want to be Blue-hassled?
In the UK, the Information Commision has said sending items over the Bluetooth airwaves isn’t regulated and as such, isn’t spam.
Thought Pie think, as long as there are some Pervasive Relations around the site and you operate a weekly refreshed ‘black-list’ (list of people who’ve refused 3 times so you don’t attempt re-send) then Bluetooth Marketing is great!
Remember, a plant in your garden is only a weed when you don’t want it.
