I'm going to tone it down a little, only 5 wall pots as opposed to 20+
See if that helps...
And also will look into wildcard subdomains so each Site URL is unique... except for the main url.... not sure if that would help or not really.
ITS DEFO DOWN TO WALL POSTS
I HAD 2 GO DOWN YESTERDAY
one after testing and sending out to 50 + friends
the other the moment i opened the post
i have had others stay allive
take the time to create a privacy pokicy with app name and a tos saying about by granting permisions you allow us to .....etc etc etc
it will keep you allive untill you go daft and post to tonnes of walls to quick
95% of the time facebook doesn't check it. A program detects too many will posts were made in too short of time period and the app is killed. imho
The worse news for your app is the removal of fb:wall later this year. Bad beats.
