I guess it did look like i was hacking since the map was surf crzyfrog, and if a player stands close enough to a thin wall, you can see their shadows through the wall because of the glitchy light engine. Also, I didn't protest this earlier because before I played tf2 I played minecraft and on small pvp servers, i always got banned for "hacking" so i had this mentality in my head that I wouldn't get anywhere if I appealed.
