Post to 50 FB accounts from 1 twitter account?

So I have a main twitter account that I use from my phone and 50 FB accounts.

Would it be advisable and possible to post across all of the FB accounts from the same twitter account at once?

So I have it working. I am using one twitter account and posting to all the FB profiles using the selective tweet app on FB. I added #fb to my sms signature on my phone so now every time I send a tweet it should update all the FB profiles... tested and working. Now lets see how long it works..
