follow adder

So ever since Instagress shut down (i know some users can still use it, but they shut me down), i am looking for a good & reliable replacement. i tried some but they are not as good as Instagress. i am now using follow adder. its nice but nice only. maybe someone knows some best practices of setting this bot? or another alternative...? i really need to find an alternative quickly. thanks!

** i did read a lot of threads here about several bots, but nothing special on follow adder, and generally didn't found a newcomer to replace instagress...
