The way I see it. It's possible, but will require a few steps.
You will need to find user(s) with high volume of like/comment ratios.
Grab their photo(s) id. [You can use iconsquare. No need to login to their site]
Input the photo(s) into FL and scrape users from it.
Once you have your list of users, setup the 'FLC:Username' feature in FL to have it follow,like,comment on all the users on your list.
The user list will only contain the username. You will need to use Excel to create two files and import them to FL per the FLC method. The two files will consist the query string for each users below. More info about 'FLC' can be found in their user guide within the software.
"Username","Relevant"
"Username","Normal Search"
