You cannot appeal a CS2 game ban.

https://help.steampowered.com/en/faqs/view/4E54-0B96-D0A4-1557

CS2 game bans can be issued for, including but not exclusively:
* frequent irregular gameplay as detected by VACNet AI or by other means, this includes premade matchmaking with a cheater repeatedly or cheating committed by yourself,
* incessant griefing by verbal abuse, in-game physical abuse or other unsportsmanlike conduct,
* botting and automation,
* manipulation of matchmaker and rating,
* disruption of gameplay on the technical level (such as DDoS attacks or causing crashes)

CS2 game bans are both permanent and non-negotiable.

In accordance with section 1 C of the Steam Subscriber Agreement, you are fully responsible for all actions on your account, no matter who used the account. This includes actions that occurred as the consequence of fraudulent account access by phishing or malware, be it input relay, session token theft or any other method that granted a third party access to your account.

Nobody gets hacked, they simply hijack your account when YOU use your Steam password with external sites.

They are not the ones using their Steam account on non Steam sites.

Due to not taking proper care of your account, were the skins worth it?

Not Valve's problem you gave away your login ....

"They killed Kenny!"
