Talking about fearmongering new users here.
This was a well known issue over the years with the unlimited plan (which is getting removed, and only already existing unlimited users will be able to continue purchasing), basically if you play for 9+ hours or so, the system can think that you are using some sort of exploit/script of putting inputs by software to avoid the 30 minute forced timeout feature if you go away from your computer.
As we learned yesterday, this was the reason the unlimited plan was removed, because people just abused the unlimited plan, at least those who use it legit can keep it, though new users will never be able to experience it(or at least not in the launch).
If you did not do anything bad, you are safe. You can relaunch your skycomputer and continue playing. Your account has been flagged, they will manually view the logs and if you did nothing wrong, your account will never get banned.
This is an automatic process. There are users who told their stories on Reddit whose accounts have been flagged around 6-7 times, all the time legit uses, and they were not banned.
They were planning to implement a new captcha system which would remove the need of the auto check, but because of abuse, Liquidsky instead decided to get rid of Unlimited(not for all, but for new users), so probably the captcha system got scrapped as well because of this.
No deletion required. Liquidsky didn't creep out because of the mods, it did because of the long playtime. One of the big selling points of Liquidsky is that you can have a cloud pc, and mod whatever you want or do whatever you want (as long as its legal).
