Create a Facebook bot for fanpges

I need a facebook bot to deal with post likes through fanpages. Here is more or less what it should look like: In the setup file you put your facebook login and password. The bot then logs onto the account and access the first fanpage from the list of all the fanpages the account is in charge of. After that, it access the fanpage news feed (not the wall with posts, but the posts from other fanpages, this fanpage have liked) After that the process of liking the posts starts (3-5 posts per fanpage) The bot chooses intervals between likes randomly (3-7 seconds) When all the posts have been liked, the bot switched to the next fanpage from the administrator list and pauses (random time between 3 and 5 minutes) The process starts again until the bot is stopped or all the fanpages are done. Requirements: The bot must work for up to 12 hours. It can be written in whatever code you wish It can choose the fanpages randomly or alphabetically. And the most important- it have to work 
