Follow Liker for one single account?

Hey guys, not sure if this is a common question or not but can't find anywhere with good info. I only have one account, which is in a fashion subgenre, so I'm not looking for a lot of profit except from my bigcartel store which I promote like once a week. I just have way too low traffic (3k followers, 5-6 comments per pic and around 100-200 likes) to be able to promote it more without annoying somebody.

TL;DR:
Should I go for FL if my goal is to boost one single account with real followers and actual engagement?

no its not worth to buy FL for single account... try instagress instead... it offer 3 days trial as well... if you want go go for FL buy unlimited license
