A few years back. I used to play MW2 on pc and got banned.

There was a thing called AlterIWnet which basically got around it

Just googled it, its been patched but I think people have found away around it.

Good luck!

First thing if you used MW2Liberation you would have been banned.
There is no way to bypass a VAC ban as it stops your
steam ID connection to the servers only way around would be to create a new account and buy MW2 again.

If you want to still host modded lobbys you could still use MW2 Liberation but thats only on a private game.

There are multiple private server networks for the game if you still wish to play it.

Source : I used to be a big part in the modding community for MW2 created multiple Mod Menus and etc and have been banned on around 20 accounts.

I really don't wanna buy MW2 again, i can't afford that a.t.m. and i don't know where to post I'm hosting for MW2 pc...

Not many people are looking for mw2 pc lobbys anymore you could try doing the old zombie mods.
Where you have to survive waves of zombies.
