User can upload photos over the limit through Story form

I limited maximum photo upload per day by 5 in user profile type. But users are able to upload unlimited number of photos through Story form.
For example, I can drag'n'drop bunch of photos (more than 5) to the story form and all the photos are uploaded successfully. If I try to do that again the system displays a message that I reached the limit.
I think that such behavior is incorrect and upload limit should be verified before uploading a photo. I mean that if I drag'n'dropped 10 photos into story form only 5 of them would be uploaded successfully.
Also after uploading the user can discard the posting of the story, but photos have already been saved in story album anyway.
Moreover, points are also added for each of the photo uploaded by such 'hack' method.

Thanks,
Timur
