    I need a piece of software that monitors a specified instagram user"s feed, and reports back to me (via email) when another specified user comments on their feed.i.e. User"s feed to monitor: @maryCommentor to monitor @bobMary posts a photo of a dog at 10:00amBob comments on Mary"s dog photo at 2:00pmSoftware sends me an email with a link to the photo, a copy of the comment, and the precise time that Bob"s comment was made.This seems difficult to monitor as Instagram doesn"t seem to publish the time a comment is posted, so this would require monitoring of the feed on a pretty frequent basis.The software could be cloud based (that"s probably best), or could run on my desktop (mac) if easier.
