I have started a new ecommerce website selling dropshipping item. Some of these items are dirt cheap and I can sell them through ebay and gain higher profit so I started to list my item on ebay. Everything looks fine and I left the item there for a few hours. When I get back, I tried to test the litecoin cpu miner at my laptop (the one I used to upload my listings) and suddenly ebay emailed me and said that " recent activity has raised security concern" dafuq is that? Ok, maybe I was wrong about the mining thing. Maybe it was caused by something else. But have anyone encounter this problem before? If yes, remind others that do not mine any cryptocurrency while selling anything at ebay.
