The stores that can get you caught are the smaller ones or the ones that in the past already did some investigation thing and cooperates with police. Also., it depends on the country. I know that backmarket uk (I'm not from there, but I have friend who lives there and does SE) is doing investigations with the police, if you do anything with the tracking, they will require some personal information and even a photo ID, proof of address and police report to get a refund. And there is a high chance that you would be just reported to the police. But you have to be dumb to give this information if you see that you are screwed. Doing SE you have to keep your private information for yourself and don't put it into every site you do SE, because it would be the easiest way to get like "arrested" if there was any chance. But DNA/EB is getting harder to do because of the need to get a police report to get a refund for it. So it's more a chance to you would get bored of going to police station or their online website to fill a form that you had your parcel stolen every time. Then you would get caught doing SE.
