Main types of bans:
Shadow ban - your account still exists on Reddit, but all comments and posts you make are invisible to other users, and all upvotes are not counted.
Permanent ban - occurs after a shadow ban, logging you out of your account and preventing you from accessing it.
Preventive ban - if you log in from a different device or IP address after a long period of time, you can change your password using your email and continue using your account. If you don't have access to your email, your account is essentially unbannable. Even if you try to change your email, the code won't be sent to your new email.
Bot bouncers and other bots can also ban you from a specific community. This won't affect your chances of being banned by Reddit itself, but you will no longer be able to post or comment in the communities where you were banned.
Anti-evil operations - content removal by Reddit moderators, often without the ability to approve their content even from a sub moderator's account.
Content removal by Reddit filters - automatic removal by spam filters; in this case, content can be approved from a sub moderator's account.
The most common reasons for any type of ban:
1. Spamming the same link in large quantities.
In this case, the link is highly likely to be blacklisted, and all accounts that posted it will receive a "red flag" from Reddit. Several such "flags" will result in the accounts being banned.
2. Accumulating karma too quickly after registering an account.
In this case, Reddit will consider you a karma farmer and ban you. Try not to accumulate too much karma for your first few comments and posts.
3. Similar account behavior patterns
If you register a large number of accounts using the same method, Reddit will eventually notice this pattern and the viability of your accounts will decrease. It's important to have a large list of subs to accumulate karma and minimize repetitive actions on your accounts.
4. Using automation
Generated content or automated actions can also lead to a ban, mainly due to reports from other pushy users.
5. Using words and phrases that are blacklisted on Reddit. These may be completely harmless words, but because they're frequently used for promotion, they're blacklisted and will be automatically removed by filters in most cases.
The best defense against Reddit bans is not to focus on one account. Create as many as possible and rotate their use. This way, a ban on several won't have a significant impact on the overall picture. Constantly rotating between accounts with different karma and age will help avoid patterns.
