I just found out that Instagram released a tagging feature a couple days ago (see https://www.instagram.com/p/BMokmydjG-M/). Right now, tagging is Instagram's weakest link as far as spam detection goes because it just came out and probably isn't polished yet. Does anybody have any valuable insights on tagging and ways to abuse it while it's fresh? I'm going to run some tests later today. If done right, I don't see why a person couldn't tag either small amounts of different people frequently, or large amounts of people infrequently, especially because tagging is fresh. Let's post our tests and findings related to Instagram tagging here.
