No automated facebook mesage sender bot?

Does anyone know of any program that will send direct messages on Facebook for me ? I send 50 messages to 50 different people a day . Long story short , the conversations start the same but all end differently . Its very time consuming copying and pasting a message into 50 different windows (i like to send them all at the same time). I've searched the internet all day and all i found was rankbook which everybody says is a scam .. and Facebook blaster pro which doesn't work : ( i find it hard to believe there is no simple software for this .

The simplest way is to create a imacro, easy and fast hope that helps!
