Wow WTF...

The only thing that I can think of was that I drove my friend's armoured car.

It usually takes quite a while to be able to get enough money to buy an armoured car.
So, could it be that when the Rockstar anti-cheat programme detects a low-level player driving a high-level car, it decides that the low-level player must therefore be a hacker?

If so, that could explain what happened with my original 30-day ban.

This is crazy stuff.

Today, all I did was:
1) Be in a general server for 2 minutes, waiting for a friend's invite to a friends-only server (I encountered no other players whilst I was in that server).
2) Play in a friends-only server. Did some VIP missions - actually, my friend did all the work, because I was back to level 1 again and so was constantly being killed by the police.

Then, after 65 minutes of gameplay, I was permanently banned from GTA online.
What the ??? This is outrageous.
It was so crazy that I had to laugh at the ridiculous nature of it all.

And now I'm permanently banned - for not cheating.

I suppose the real question is:
Why did they wait 65 minutes?
If they're going to go full potato with their banning madness, then surely it would've been funnier if they just banned me 1 minute into the game instead.

Wow, Rockstar, just wow.

Even though I was very angry and cheesed off at Rockstar over being falsely banned for 30 days in the first place (see https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1340591382) , I agreed to play it again.

Following the 30 day ban, my entire account was wiped.
Not that I had much (because I'm not a hacker) - I was only level 33, and had just bought my first apartment and my first armoured car (it took 70 hours to get enough money to buy them).

I've never hacked or modded.
In fact, I've never had a hack or mod on my computer, so it's not like there was one lurking on my PC that could have triggered a ban.
