Today we’re introducing a couple changes to decrease spam on Instagram. There are so many excellent and genuine interactions that take place in the comment feeds on photos, and we want to make sure those conversations aren’t interrupted by spammy comments. Now, when you post the same comment on multiple photos, you will receive a warning (red exclamation mark) indicating that your comment did not post successfully. We’re also filtering for certain words and phrases. We hope these changes encourage more genuine interactions between users. If you have any feedback on these changes, please let us know.
