I will be explaining this thread here Firstly I have tested this on my account, I normally range from 200-300 likes. When I did this for 2 pictures both got over 1,000+ likes! Today I tested it again without and I go about 300 likes again. Basically what this feature does it puts your post on the top of people's feed (not a fact, just from my tests) Here is a tip though: Just put that in your caption (won't work if you put it in comments) and then wait a few minutes, and then edit your caption to something less spammy! You will get insane engagement! Also this obviously won't work if you have a small account to being with, I would say this would work with accounts over 5k followers.
