How to auto comment on facebook page posts

Hi all,

I was looking for a working way to automatically comment my messages on the posts of facebook pages..

My boss wanted me to learn the way to send spammy advertisement comments on the posts of facebook pages, so I'm here to ask you.

I've found some but most seems old threads and i don't know if they are still working..

good question, tell me if u ever knew the answer

Any idea guys what kind of bot/skrypt can we use for that ?
