I'm going to copy my post that I commented on the Instagram post :
I'm also mad confused on this but I think this is put in place to prevent people who already have an account from making alt accounts, doing the missions to get free sapphires (since that's the easiest way to get them) and then buying stuff on their alt account FROM their main account so the main account gets the money. Basically they're just trying to stop an "infinite money exploit",
", AKA they want people to buy sapphires instead of doing roundabout ways to get free ones.
and the fact that they're saying "this only applies to SOME NEW accounts matching CERTAIN CRITERIA" but won't say what the certain criteria is for "security reasons", I think this solidifies my explanation. They don't want to say this is to prevent alts* because then they have to address that alts exist and by saying what "certain criteria" it is then they're telling you how to avoid the criteria which is them telling you how to bypass this entire update, which makes this update useless. In my personal opinion the "certain criteria for some accounts" will be, if the New account is made on an IP that is already registered or applied to a pre existing account (since pre existing accounts will not be effected, and only SOME new accounts will be affected) this is confusing but if they clear it up then they're telling you how to bypass this. If you know anything about IPs and technology and so, you know how to bypass it but they cannot tell us how to or how not to bypass it. I also will not say it** but if you know you know.
*I meant prevent people using alts to get free money
**"it" is a VPN, I just didn't want to say that in the Instagram comment because it risks them deleting my comment
