I made an unfollowing macro recently that works on statigram. just login to your account through statigram and let the macro do the rest.
you'll have to change few things in the macro because the forum doesnt allow posting url and images:
on the macro- 1)change all "cccc" to "http"
2)change all "ppp" to "png"
THE MACRO:
****************
TAB T=1
TAB CLOSEALLOTHERS
url goto=cccc://statigr.am/viewer.php#/myFollowings/
wait seconds=3
TAG POS=1 TYPE=IMG ATTR=SRC:cccc://statigr.am/images/unfollow.ppp
TAG POS=1 TYPE=DIV ATTR=ID:general-content
wait seconds=2
TAG POS=1 TYPE=IMG ATTR=SRC:cccc://statigr.am/images/unfollow.ppp

wait seconds=2
TAG POS=1 TYPE=IMG ATTR=SRC:cccc://statigr.am/images/unfollow.ppp
TAG POS=1 TYPE=DIV ATTR=ID:general-content
wait seconds=2
TAG POS=1 TYPE=IMG ATTR=SRC:cccc://statigr.am/images/unfollow.ppp
TAG POS=1 TYPE=DIV ATTR=ID:general-content
wait seconds=200
****************
the macro may stop unfollowing due to the IG limit, so try changing the waiting time from 200 to something higher, so it would continue unfollowing afterwards without breaking the limits. if it doesnt, you may even lower the waiting time...
enjoy!!!

(by the way if you have any good follow/like bot that works for free, such as instaflow, ill be happy to hear about it
