Jarvee o mp are not dead but they are no longer the tool that they used to be, there are some better alternatives now.
They can still work with lot's of headcache, you need to use the new full api emulation, which is better than eb and for this to works you need to use a scrapers to reduce the api calls made by the main account and because the new api still doesn't support all function, atm only follow/ufollow/like and comments are supported.
I still run some accounts for testing purpose, but for client growth is madness, here are easier and safer way to grow, need to adapt to the changes.
