BF4 Cheat.

I just want to know before I consider purchasing the BF4 cheat some things.
Those things are:
-Bans
-FPS Drop
and
-If It's Working

[BANS] So I want to know how the banning works in battle field 4, I couldn't find anything about it so i'm hoping somebody know's.
Let's say I want to cheat and I go in a game using the "Server Browser" and I get banned from that server. Will the ban be only from that server
or will it be from BF4 in general.

[FPS DROP] Will my FPS Drop while cheating? I normally get around 100 using horrible settings due to my shit computer.

[DOES IT WORK] I see a lot of threads for help on the BF4 section saying that they can't inject it or when they do, they get an error.

Thank you if you answered my questions and thank you if you took time out of your day to read my concerns.

Sincerely,
Nick
