Instagress Is Too Slow Should I Buy FL?

I am building 2 authority accounts for different niches.
I think instagress is slow asf even with fast setting I can follows max 650 to 700 people in 24 hours. I can hardly get like 100 to 150 followers in each accounts but the main advantage of using instagress is accounts never gets ban.
I have never used FL. I talked to some of my friends they are using FL for just Instagram followers hacks and that spamming crap.
Is there anyone building authority accounts with FL? Are there more chances of getting banned with FL?

instagress is slow but it makes sure you stay within the limits of ig

FL is the single tool which is worth buying for instagram. period. I said that like 50 times

FL is arguably better than instagress, however they have some functions I would like in FL.

However, if you know how to use FL, it is by far the best product out there. Just be careful not to get banned because it is REALLY powerful if you know what you're doing.
