How do I decrease my fraud score?

[DroidSoul]

So yesterday and today I have attempted to cashout egiftcards but failed, the payment went through but 15 minutes after I get an email saying my order is cancelled because of fraud risk.
I have checked my fraud score on ipqualityscore.com and get a score of 65 "suspicious", also says proxy/vpn detected + the location is different to what whoer and amazon detects - san francisco, but my zip detected on sites like whoer is san jose.
How do I lower this fraud score? Do I simply have to change IP, currently I am using bestproxyandvpn.
