Re: Cast iron security
If you want to overload servers, you're going to have to do a lot more than that. Let's run some numbers; I'm bored.
Let's assume each message has a thousand characters. Manually sent once per day to ten people. That makes your storage impact 10000 bytes for payloads and ten metadata frames, let's say those are another thousand bytes. Your friends each have ten friends who will do the same, not including you. So we now have a total of 111 people doing this. Current daily traffic is now 2.2 megabytes (using decimal). At Azure storage prices, that would cost Facebook about $0.00019 per day for all of you combined. If you do this routinely for a decade, that takes it up to $0.68. That's if they never compress your messages or delete the ones which are obvious garbage.
But what if your friends can find other friends like a multilevel marketer's sales pitch? Well, if they go out four levels with ten friends each time, you now have 11111 people all spamming the system. Over our decade, that's a storage bill of $69.00. They will not notice.
