Gosh, yes! Hold the paper up so your viewing angle is more from the side than above. Tilt back and forth until the light angle is somewhat slanted. See? When I cross something out, I use the same pen, I use straight lines at various angles, then lots of circular motion after that, like a string of cursive “e“s. Still, when someone is writing, their movements are deliberate. Crossing something out, the movements are more casual. Spotting the difference is not so difficult.
