Since 3 or 4 days ago i'm not able to like any photos from any token, I think they blocked me to like. I still can follow/unfollow users via my application. I also can like photos via instagram iOS app. This is the error i have:
"meta": {
"error_type":"APINotAllowedError",
"code": 400,
"error_message":"you cannot like this media"}
Do you know if they will unlock me or it's permanently?
Instagram changed the terms for using POST and DELETE requests. You can read more about it here http://developers.instagram.com/post/116410697261/publishing-guidelines-and-signed-requests
If you want to request access to those endpoints you can do it here, if your app is qualified.
