However, they need some modifications if they don't want to piss off their users in implementing it.
Here's my suggestion(s):
Let users specify how much it should cost to contact them, and let them keep a percentage of every dollar over $1. Then let marketing messengers set a 'maximum cost' amount - if it's too costly, they won't send.
Don't want to be messaged? Set your price insanely high.
Don't mind being messaged as long as you get something out of it? Set it to $2-$5.
Win for everyone.
Then again, they already deal with this with fb credits, so maybe this wouldn't be too taxing to deal with.
For example, there are probably few people willing to launder money at a cost of 90%, and 10% seems like the amount FB would pay.
Would there be 1,000 businesses willing to spend $1 million each to send a message to a million people? That's $1 billion. Can messages be targeted enough and give a good enough ROI? Will users be pissed off and dismiss businesses that put ads into their private inbox?
More negatives than positives, IMHO..
I'm usually anti-FB but I'm curious to see where this goes.
E.g. If I've sent `s` messages per day averaged over the last N days, the next message that I send should cost (rounded to the nearest penny):
1.01^(s-1)
That's the barrier to entry imposed by a dollar on direct marketers.
When ads are targeted well enough, they stop being spam, and start becoming a welcome service. The question is whether they have reached that threshold.
