Hello Dutchman, ccw808.
I am a Russian software developer, and I got a lock in MTA, since I am currently working on the handles analyzer (Improved version of the task manager), I very often leave the MTA open so that I have more hours on the server. During development, I run temporary builds of my software and apparently the anti-cheat considered it a danger for the game's handle.
I received not an automatic ban as far as I understand. See screenshot below.
