I'll quickly just answer your question here like any minion or professional here at MPGH would.
Whenever you use a hack for any game, you accept the risks that you have a chance to get banned at anytime and the coders and people here at MPGH are not responsible for what happens to you or your game. Hack at your own risk.
Now for the vac banning policy. I have never been banned (I will share my secrets further down) and have seen people on MPGH post about 1 day bans and up to 3 week banning delays where they put you on a list and will later ban you. I am not 100% sure on how this works. Getting caught all depends on the hack and if vac has been updated to detect that hack. There is no warning sign that says "VAC sees your hacks" or anything so we can not be sure what is and is not detected.
Now can I suggest wall hack is not the way to go. A safer and easier way to play would be to use house's texture hacks (now named chromatix). This hack is 100% safe as vac claims they will never ban for texture hacking. You can remove foilage and change player skins into colors like cyan.
Other hacks such as "Rapid fire", "Quickscope", and "Fast knife" scripts are all 100% safe to use and give you an amazing advantage over other players and you can not be banned for them.
I just told you how NOT to get banned while cheating. Next you can take it a step further and get a vac proof aimbot.

That is an aimbot that uses texture hacks to find players. I have personally never tried it but looks decent.
Please know that there is a minimal chance you will ever get banned if you used all this together.
Hope this helps you
