There is an e-mail program called Goowy which is one of a species of software I call ‘landmine-ware’, which is to say during the sign up process, on one of those bits no one actually reads, there is a yes-by-default opt-in box that allows the software to do something very few people would agree to if they actually noticed what they were being asked to agree to.
A friend of mine just signed up for Goowy and as a result Goowy just imported her entire contacts list from Gmail and spammed them all (including me) with invitations to sign up for Goowy. Now as this was technically permitted by the default-yes selected check box, there is nothing clearly actionable about this. However as no one would usually agree to their entire email address book being spammed by a third party, it would be fair to say Goowy counts on people just not realising what they are ‘consenting’ to and thus relying on people’s natural tendency to not carefully watch every step they take (hence my description of Goowy as ‘landmineware’)
Now just to spare all the obsessive libertarians reading this from getting their knickers in a contractarian twist, just because something may not be immoral theft (i.e. Goowy did not ‘steal’ permission to spam in your name) it does not mean it should be socially respectable to trick people into doing something either. Yes, ideally we should all read every line of the disclaimer on every single thing we sign up for on the internet. Yet other than a few obsessives, no one actually does that in the real world as there is a general expectation that nowadays companies understand how much spammers are hated and what bad PR can be generated by acting like a spammer. Sadly Goovy suggests that this expectation is not quite as dependable as it should be.
At the very least, tricking people into in effect becoming spammers gets people like me writing nasty things about any company who would do that. In short, any company who resorts to abusing what is typical customer behaviour should not be trusted. Even if tomorrow Goowy announced it was going to make that option default-no rather than default-yes (i.e. permission to spam your entire address book of contacts), I would not allow them to be anywhere near my personal email and I suggest you do not either.
