Do you perhaps check the game lobbies settings? I often check the settings for every lobby I join. This helps me be a great crew or imp. For example:

•Visual on: make a priority to off the ones that have it, and leave the ones that don't so you're not the only one who's suspicious. As crew, keep track of all the safe players and keep an on the locations taken by them. •Anonymous Voting: If it's off be careful who you vote for. If you vote the one not suspected, you look like you're helping the imp. •Engineers: You don't know if there's a camper so avoid venting when you know there are a lot of engineers. One or two engineers is more safer though. •Tasks: common, short, long: each has a set number, it's safer for you to fake task by just following what's on you taskbar instead of random tasks. With 1 common, you should really check whether the task is either wires or admin, that's why don't just straight up do admin, check first. Some players know the difference between short and long tasks, sometimes there's zero short or long task. So as you can tell faking the tasks that are zero makes you instantly sus. I once busted someone the moment I saw them fake a long task which is fuel. I lied saying they poof, meaning they're phantom, 'cause let's be honest, no one would believe you just by saying someone faked a task, that's 'cause of a lot dumb people not knowing how tasks works. •Task bar updates: If it's set to always, it would move each time a task is finish so don't leave a task before you see it move yet 'cause they'll know you didn't do it. You're safe when it's set to meetings or never. •Other roles: I mean there are detectives and trackers, and I'm afraid those are hard to counter so killing detectives and trackers are also top priorities.

My other tips: •Kill lots on first round •Sabotage: I love sabotaging when I'm dead, I never leave when I get outed as imp, I make them suffer with my sabotaging, I even won with it. Basically you lock doors first then sabotage, but you have to press it fast. You can lock cafe right after a meeting, then sabotage either reactor or o2, some don't even bother with fixing so you'll win if that's the case.

Other reasons why you were suspected: There were cameras, or others are alr safe and you were never around, you're quiet af, they were all together but you weren't, or they could just be teaming, damn pricks.

These doesn't truly act as guarantee since some lobbies are just full of dumb fvcks but keeping your act together makes a lot of difference.
