Can you get banned for VPN on COD?

I've heard rumors that using a VPN on Call of Duty (COD) can result in a ban. Is this true? If so, what exactly is the reason behind it? And are there any specific VPN services that are more likely to trigger a ban than others? I'm just trying to understand the risks and ensure I'm playing safely within the game's terms of service. Can you clarify the situation for me?
