As far as I understand, these are FB hacked accounts of REAL people that you deactivate business notifications on their accounts in order to create a BM and use it on their behalf without them knowing.
For customers: If something goes wrong, are you sure you wont be tracked using your Shopify store personal details? your domain name details? Your company name?
This is totally BlackHat and I have no problem with that, my problem is that the OP is advertising this as a WhiteHat solution for people that might have registered their company to their name and gave their personal information when creating their accounts and risk to get caught easily if any legal action was taken.
OP, Can you address this please? I have a problem with FB too, but this solution I can't recommend for legit businesses.
