Ohh that’s nice finally i can block one time the sex PM Scams and never get again a pm from this Bot source. Amazing feature from Instagram.
And the best is my ex cant create new accounts to stalk and text me. 
I dont think so that it will not effect the grow strateticy. If someone dont have interest for your or client products and he block u an other account cant change the situation that this person will never be a customer. In the end its good for us because we dont lose API Cals to try again with a new account to text the same person that dont like the service. I think i it will bring better results.
In our country we get phone free to 4G data tariffs so in the end if i have to change faster the Phones i can make more money about selling the phones 
@Micky are u using the phones just for create new Accounts and to make the worm ups? Or do u use also the phones as proxy server?
