@chris Miller - funding spam
We use an SMS system where I work, essentially an old Nokia phone with a Pay as You Go sim, hooked to the back of a monitoring system. Top it up with £5 and purchase an Unlimited Text Bundle from Orange using said £5 credit. Tadaa, "unlimited" texts for a month.
Usually, we send 10-15 sms a day to systems engineers, but one evening my shell script went haywire, and around 1000 sms later, I finally got into the office to stop it. - Orange happily let me continue sending for the rest of that month though, without so much as a "Please stop" message back
So even if you're only going to get your 1000 for £5 that's £0.005 per text, likely you'll get many more. How much do they make in referral fees if just one of those 1000 hits a customer who feels the need to contact an ambulance chaser?
Much cheaper than cold calling people, and none of the aggravation of employing a room full of call centre workers
