helloskitty125, what i've just read?
To begin with, VAC doesn't ban right after hack is detected, It uses delayed ban system, so if you were banned it's because the moment you used hack in past that hack
was already detected or the it's signature was saved after injecting and been analysed some time after when the hack was blacklisted, and so your acc was marked for delayed ban.
Furthermore, VAC doesn't ban for hack files, it only bans when they're being used. Surely after VAC3 was introduced it started scanning some non-game files on your system as some people discovered, but if it would ban just for what it find then my acc must be banned years ago as I have a plenty of hacks which I downloaded while making research on their code.
Moreover, this exact app, Universal Tunable Xhair, won't be detected as they'd have to mark all autohotkey scripts bannable to do so, and it will result in a huge shitstorm as many people use autohotkey scripts not even related to gaming.
On top of that, I'm personally using this script for 4 years and plan to continue using it, and it's the only script I posted on this forum which I actually use because I'm 100% sure Volvo won't ban it.
Why even ban for such thing as external crosshair? It's totally harmless app which gives you not even advantage over other players but only ability to customize and adjust your gaming experience. Actually, if game developers didn't consider us gamers fully retarded the'd implement something like that by themselves built in game settings.
