Listen, if you REALLY want to cheat in Tarkov and get away with it, you need to invest in a DMA card. DMA providers have come a LONG way. The provider I use gives me everything an internal can do: aimbot, unlimited stam/strength, loot through walls, radar, chams/ESP, etc. At this state, DMA is undetectable and will be for some time. I have been cheating for over a year on my EoD account and no ban. With internals, once you inject, it's not will you get banned. It's when. Cause you will get banned. Doesnt matter if its private or not. With DMA you are not injecting anything on your main PC. Everything is done on a second PC. This also helps with protection.
Now, the cost of this is about $600 for a DMA card (if you can get one from a seller and not re-seller), and the price per month for what Im using at the moment is $65 a month. Most of these high level private cheat providers are going to charge you $100 a month or more. It is not worth it. You can also pay a lifetime fee for this service which is $600. So all in all, you pay $1,200 (if you want lifetime) and will outlast ALL internal users.
Now, I'm not saying you WON'T get banned. This just protects you against BattlEye. If you go through each lobby and head,eyes everyone, you will more than likely get a manual ban from BSG after so many reports. Now, I've been meaning to buy a regular account and do this myself just for science to see how long it would take BSG to ban me, but I haven't done it yet.
