It’s because they locked labs behind a paywall and money is irrelevant to cheaters.
If you know that you have an advantage over other players and there’s a specific map that has a larger and better loot density than others, that’s where the cheaters are going to go.
The paywall hinders legitimate players but doesn’t hinder cheaters as they beeline to get a card and then use their cheats to farm profit.
This leads to the number of legit players going into to labs to be less so you’re more likely to encounter someone who is cheating.
More people are cheating in this game than most of us realize, all of the major cheat providers that offer a cheat for EFT are online. Why not monitor labs for the time being and just start applying manual bans to the cheaters that get caught?
