COD: Mobile has few easy ways of knowing if your team or enemies contains bots.
Check Their Name
If they have a name like PotaTO (Weird Capitalization) most likely that they are bots.
Give a Thumbs Up
After a match give them a thumbs up and if add friend request popped up that means it's a real person.
- If you've ignored someone in the past, you will not see the add friend window.
