There are four main types of bans in CS2: a temporary competitive cooldown, an Overwatch ban, Untrusted status and a VAC ban. Cooldowns for kicking, abandoning a match or team damage expire on their own after anything from 30 minutes to a week. VAC and Untrusted bans are permanent and, in practice, cannot be lifted. Below is what each ban is given for, how long it lasts and whether you can appeal it.
All of these systems date back to CS:GO and carried over to CS2, with some changes: Overwatch, for example, works differently in CS2. So, the game has 4 types of purely in-game bans:
competitive cooldown;
Overwatch ban;
Untrusted status;
VAC ban.
A VAC ban is the most serious penalty in CS2: it is almost impossible to lift, even for a pro player with an impressive tournament record. That is why no third-party program that interferes with the game is worth the risk to your account.
What Bans in CS2 Mean for Your Account
Overwatch Ban
Let's start with Overwatch bans. Unlike the others, this restriction is not issued by an automated system but by players themselves. Overwatch in CS:GO was a group of experienced players acting as investigators: they reviewed replays of suspected players and decided whether the rules had been broken. In other words, their verdict directly decided whether a player got banned.
Overwatch in CS:GO worked like this:
players report a suspicious participant in a match;
an investigator sees an Overwatch button with an unreviewed case in the main menu;
they watch about 8 rounds of the replay (around 10 minutes);
they give a verdict on the suspect's fair play, and the final decision combines the votes of several investigators.
Accusations fall into 4 categories, and for each one the investigator picks one of two verdicts: "insufficient evidence" or "evident beyond a reasonable doubt." If investigators are split or most find the player innocent, no ban is issued.
The verdicts are:
"You have been convicted by Overwatch" for a minor offense (such as griefing): a temporary ban, usually up to 30 days; repeat offenses are punished more harshly;
"You have been convicted by Overwatch" for a major offense: cheaters and users of prohibited software. This ban is permanent and cannot be lifted.
CS2 went without classic Overwatch for a long time, and then Valve launched a new version: a portal where reviewers label replays to help train the VACnet anti-cheat, but their verdicts no longer ban anyone directly.

Competitive Cooldown
A competitive cooldown expires on its own, which makes it the mildest restriction. You can get one for:
dealing around 300 team damage in a match or killing 1 or 2 teammates;
abandoning a match after it starts;
kicking other players by vote too often;
staying AFK for more than a few minutes without warning anyone;
disconnecting because of connection problems or a game error and not reconnecting in time.
These offenses lead to bans from 30 minutes to 7 days, and each new cooldown is longer than the last: roughly 30 minutes, 2 hours, a day, a week. The counter resets if you play cleanly for a while, but it is not worth pushing it: frequent abandons also hurt your account's reputation.

Untrusted
Valve's servers assign Untrusted status when they detect interference with the game: third-party programs that inject into its process or modify its files. An Untrusted account loses access to official matchmaking and competitive modes. Unlike a cooldown, it does not expire: in effect it is a permanent game ban, just like VAC.
Can Untrusted be removed? Only if it was issued by mistake: there have been mass false positives after which Valve lifted the bans itself. You can contact Steam Support, but do not count on success. To avoid this status, never run programs that inject into the game. Regular community servers that hand out skins through a plugin like !ws do not count as a violation; learn more in CS2 servers with skins.
Account trouble often starts not with cheats but with scammers: fake websites, "free" programs and forged trade offers. For how to keep your account and items safe, read how to protect your inventory from scammers.
VAC Ban
A VAC ban is the most serious penalty a CS2 player can get. It permanently blocks access to anti-cheat-protected game servers with no appeal, and a ban notice appears on your Steam profile.
VAC is used not only in Counter-Strike but in other Steam games too, for example:
Left 4 Dead 2;
Team Fortress 2;
Counter-Strike 1.6.
If you are looking for how to remove a VAC ban in CS2, the answer is simple: you cannot, it is permanent and not subject to appeal. It is given for cheats and other software that gives an unfair advantage and breaks the game's balance. Technically you can keep playing, but only against bots and on servers without VAC protection; official matchmaking is closed to that account.
VAC (Valve Anti-Cheat) is the Steam system that detects prohibited third-party software. It is not perfect: some violators play unbanned for a while, because new cheats appear faster than the protection is updated. Sooner or later, though, ban waves reach them too, so risking your account and inventory is never worth it.
