if i use this program in BF4 Can I get banned by punkbuster or FF?

Does bf4db consider this a cheating program?

I assume you want to make a crosshair on your game? Yes, we consider that cheating.

It is also against the ToS, which states:

6. Rules of Conduct

When you access or use an EA Service, you agree that you will not:

...

• Use or distribute unauthorized software programs or tools, such as "auto" software programs, "macro" software programs, "cheat utility" software program or applications, exploits, cheats, or any other game hacking, altering or cheating software or tool.
• Engage in any other activity that significantly disturbs the peaceful, fair and respectful gaming environment of an EA Service.
  

...

As the crosshair is not originally in the game, it alters the gameplay and can be considered cheating. It also creates an unfair advantage, especially in hardcore, and thus disrupts a fair gaming environment.

In short, you can get banned by Punkbuster, FF and EA.

Go to the nearest police station and ask if  killing  someone  will get you into jail..

I think he means changing the icon of bf4.exe ...

That's funny lol  :D
