Aim Assist user is usually a bad player, doesn't know about anything in-game. My method to spot if someone using Aim Assist is: Look at their positioning.

Upload the replay with a screen shot with a nice little report in the reporting section so when they get around to it they'll get banned. Automation doesn't though so you'll see lots and lots of hits on land along your intended path. A player would not even fire past your bow if they know you're going to hit land and stop.

What will happens it youll see a whole lot of shells keep following your intended path along the land mass. When you smack into the island and suddenly stop their mindless auto aiming will have them either spamming their fire buttons or automatically firing with the cheat. You will tank damage but it's fine, you're just proving they're cheats. My primary method is dupe them, turn towards an island at full speed. What I want to do is explain to you all how to play so you're also able to spot players cheating. I've been playing for a long time now and know and understand the firing patterns of people and because of it it's easy to spot players who are using some form of aim assistance what ever.
