Arma 3 duping logs?

I was wondering if anyone has any insight onto the type of log's that would get dupers caught on an Arma 3 server, not sure if it matters but the server I am wondering about does run infistar.
Would it be obvious in the log's somebody is duping even if they don't sell the items and just uses them for personal thing's, base building etc, or only sell a couple of the items once in a while?

I am just wondering mainly what the best method would be to avoid being detected by log's or if they just pop up with a red warning about me duping.

been duping on ccg for like 2 days then i stopped doing big dupe ( selling 20 lvl 4 stolen flag on exile) and ive just duped food ammo fortification upgrade and havent been ban yet. Im pretty sure that selling a rare item a high amount of time will give a warning to admins. Best I could say is to actually sell something expensive that you dupe then buy alot of different stuff and the sell an expensive item again just to make it look more legit. Also, your method might get log depending on how its done
