not going to list applications (1 not to shame them and 2 it be one pretty long list) but if this is what i believe it is. Loads of applications will need to change there practices particularly those that say ‘send 10 to unlock level 2 etc’

as this post seems to make these type of application prohibited

also those that you earn points (to pay for new items .g. Jambool Applications e.g. hug me a new hug, Growing Gifts & Hatching Eggs new format that you gain points and can buy a item with those points – this update also seems that it may stop this as well.

so basically all content from this has to be upfront and if new features or ideas are added they need to be at the start (or available to all when added)

Now Facebook needs to decide about applications with same names (e.g. Hug me) – all applications should be required to have a different display name.

also there is a few applications (developers) that abusing the service by creating several duplicate applications to get round the friend request restrictions. One valid exception is Extended Info with its More Extended Info application (its motivate aint inviting friends and there is not upto 10 of them a fictional example is apps.facebook.com/spammy_hugs then having 5 applications like apps.facebook.com/spammy_hugs4

Also consider an idea of forcing collabration that means not 200 hug application for example down to a few or applications can interwork (legally)
