Whats in your corner is either the FPS counter, Snapshot, or Server Position. None of which will get you banned. Neither will the lagometer. And afaik, mods are not bannable, unless you are hosting public prestige lobbies, XP multiplier lobbies over 4x (I think) or host abuse mods, like RAPE.
But running any of those mods privately should not get you banned. Texture mods, afaik they have no way of even being able to detect them, so texture hack all you want, just don't let them see screenshots or video of you playing or else.
