Solvedif i ..

if i use speed hack in pubblic ( i mean x10 command ) i will get banned?

Yes .

that is like asking...hey a cop is standing next to a baby. If i go up and punch the baby as hard as i can...will i get arrested?

just use the hacks in private. try to keep it low key. dont brag or boast about how fast you can run stuff or get gold soooooo fast. set a keybinding so you can toggle your stuff on/off its faster then typing and you will get use to toggling speed off when you get to town or before you leave a dungeon.
just be smart and think ...can i normally do this? if no then you run a risk of being banned so just play smart.

You will if I see your ass doing it.
I hate these fucking idiots that are exploiting shit they're too lazy to come up with and thinking they're gods...Fuck that, I'll get their asses banned or die trying.
Call me a hypocrite, I personally don't give a shit, the bottom line is I have never ONCE fucked up the marketplace, sold gold, or any other items that were obtained illegitimately except through an NPC Trader.
Sitting in public going "LOOK AT ME I'M HACKING" is asking me and thousands of others to report you, so don't get all pissy if they do.
