most of the time its common sense to not have cheat engine open while playing online JS
A little young to know?? Saying the one who says kiddo in a sentence...and no after vac gets added it detects CE because it's a common program and the code doesn't really change making it easy for them to detect...
Im pretty sure that as long as CE isnt hooked to a vac protected program it wont do anything.
You should not be banned with CE opened in background
