Followliker 0 followbacks but growing

Hi there!
i'm new to followliker and i have 4 accounts running on it,
3 of them are fine, regular follow unfollow stuff...
the fourth one though followed about 300 accounts in the last 2 days, got 0 followbacks but still managed to get around 100 new followers from unknown accounts (by unknown i mean that most of the times my account did not even like any of their pics)

a couple of things that may be useful:
The account "organic" growth before botting was 1/2 followers a day.
I got some big followers organically in the last few days from niche alike accounts.

Anyone has got a theory on whats going on?
Ig Magic, followliker not working properly, I'm unexpectedly managing a really interesting account (why no follobacks then)?

ON FL, check the followings for that account. There you will see which accounts followed back (Y) and when.

thanks for replying Colorme
how do I do that? (i'm on mac is there a difference in available functions than windows?)

but still, the other 100 followers came from nothing after i started botting, any explanation or past experiences with something similar?
