The delights of Nothern Europe

10 internet etiquette core rules:

1. Respect People's Privacy

Don't forward information sent to you without checking with the original sender first.  Use BCC (blind carbon copy) rather than CC (carbon copy) if you are sending something out to more than one person.  You might think that we are all friends online, but your friends may not want their names and or email addresses publicized to your acquaintances that they do not even know.

2. Don't Repost Without Checking the Facts

That cure for cancer might sound pretty impressive, but it will just cause upset if it is a hoax.  And urban myths just add to the noise of the internet and waste people's time.  If you aren't sure of the facts, email it to someone who does know or can find out, like your friendly Verywell.com Expert on the topic. Or just do a Google search.

3. Update Online Information That People Depend Upon

Don't leave inaccurate information online just because you can't be bothered to update your website.  If you are going to be unavailable, for example, don't leave your hours of operation online indicating you will be available.  If you can't keep your website up to date, take it down. 

4. Don’t click that link or online ad

You found a pretty cool link on the Internet and it keeps tempting you to click it. But the source of the link (website or email) seems fishy. You ask yourself: What can the bad guys do to me if I click this link? The answer is simple: a lot of things could go wrong. Just by clicking a link in an email or a pop-up window, you could turn your PC into a botnet slave, allow cybercriminals to inject malware into your device, or expose your personal information.

5. Just because it’s free, it doesn’t mean it’s safe

As a rule of thumb, paid software is almost always secure and safe. It wouldn’t make sense for a cybercriminal to limit the number of victims by imposing a paywall.

6. Keep your account information for yourself

Our credentials for online accounts, user names and passwords, hold the keys to a lot of important information, and for that reason they are the most sought after targets by cybercriminals.Using the same password for more than one site is a risky move, since if a malicious hacker breaks into just one account, he can then take over the others.

7. Report illegal activities or offending content

If you notice offending language attacks, like cyber-bullying, hate speech or any form of harassment, do not hesitate to report it.

8. What you post online stays online forever

We post photos, remarks, location updates and similar content, which we think is fine because we use an anonymous username on a small niche forum.
But niche forums are also indexed by search results, and if you reuse the username, other people can start to connect the dots. This is called doxxing, where people hunt for information about an internet user until they manage to figure out who they are in real life.

9.  Use antivirus protection before you go online

Don’t go online until you have the best antivirus protection that money can buy.

10. Create back-up copies for your important stuff

Though you may have all the security protection in the world, disaster may still hit your system and your valuable files. It may be a system crash, a hard disk failure, a ransomware attack that encrypts your entire operating system or it may be a human mistake.There are so many reasons something can go wrong for you and your sensitive information, even if you followed all the netiquette rules in the book.
