Not necessarily.
This is the attitude of criminal that isn't casual. People that refund the latest store one time and then have their info burned and can never do them again are casual refunders. A person with 10 residential drops that aren't at the same apartment complex or something like that is likely a more full-time criminal.
As far as charges go, if they're rotating drops in multiple surrounding areas, the likelihood of getting noticed or caught is low. That is, unless you do something stupid that gets you noticed. I remember there was a refunder on Leak years ago that had tons of drops in his area in the UK. He was refunding Amazon multiple times a day and selling multiple XBOX 360s or PS3's on ebay every day. Turned out the guy was funneling his money into his own PayPal account. He was noticed by the tax police in his country after PayPal reported the amounts he was receiving since it was over the threshold for reporting. Sure enough, the guy got into trouble when he otherwise may not have.
