What are the 18 rules of internet?
The "18 Rules of Internet" you mention could be referring to the rules from Anonymous, which are actually 50 guidelines to follow. However, there is a more widely known set of rules referred to as "Rules of the Internet" that initially started as an inside joke on imageboards and forums. They typically make fun of trends and behaviors found online. The first 18 rules are as follows:
1. Do not talk about /b/ (a popular board on the 4chan imageboard).
2. Do NOT talk about /b/.
3. We are Anonymous.
4. Anonymous is legion.
5. Anonymous does not forgive, Anonymous does not forget.
6. Anonymous can be a horrible, senseless, uncaring monster.
7. Anonymous is still able to deliver.
8. There are no real rules about posting.
9. There are no real rules about moderation either; enjoy your ban.
10. If you enjoy any rival sites, DON'T.
11. All your carefully picked arguments can be easily ignored.
12. Anything you say can and will be used against you.
13. Anything you say can be turned into something else - fixed.
14. Do not argue with trolls; it means that they win.
15. The harder you try, the harder you will fail.
16. If you fail in epic proportions, it may just become a winning failure.
17. Every win fails eventually.
18. Everything that can be labeled can be hated.
Keep in mind, these rules are from internet culture and not meant to be taken seriously. The context of these rules is important when understanding or engaging in online discussions.
