VPNs may help, but also using a different device, like a phone might help, also don't funnel funds or items from account to account too often. Basically, make it look like someone else is playing, like a friend. They really can't do much if you share IPs with someone because y'know like people in dorms or sharing internet, that is unless you make it obvious you're the same person.
Just be careful is really what I'm saying, but you didn't hear that from me
