If you take a moment to read the official rules, you’ll find this clearly stated:
“FlyOrDie members have the right to know if they are playing against a computer. Therefore you must declare in your player settings if you are using assistance while playing. Using any kind of assistance without declaration is considered extremely unsportsmanlike with appropriate sanctions.
You can have one human account and one program account, and you must use both accordingly. Use of such assistance is only allowed in board games.”
That last sentence is key, assistance is not allowed in games like billiards for example. The computer icon you see only relates to board games, where declared use is permitted.
Anyone using assistance in non-board games is violating the rules and risks being permanently banned.
