It is precisely these kinds of garbage tactics that app makers should avoid. Not only does it make me despise your service, it sheds ill light on Facebook, as well.
A user comments:
I got an e-mail from a friend today asking me how I know about her school from Japan.
Schoolfeed sent her a message UNDER MY NAME, about her school.
I have since found out that they’ve spammed several of my Facebook friends with messages UNDER MY NAME. I deleted my Schoolfeed account and will NEVER go to their site again. NONE of the messages showed up in my Facebook history so I have to laboriously go to each friend’s home page to find out if they got any messages from me.
Facebook are happy to make a buck and will never answer an email with complaints about these stealth app tactics.
