Online etiquette

Libel and defamation: do not post online false information or insinuations about a person that could cause damage, suffering or contempt. In other words: do not publish online any defamatory material or anything that you would not be willing to express in any other context and be prepared to take the consequences. Also, do not post online any information, insinuation or image of a person that could cause damage, suffering, or contempt.
Copyright and trademark law: do not distribute on the Internet any material – such as music, text, photographs, drawings or trademarks – to which you do not own the rights. Unauthorized distribution and use of such material may lead to legal consequences.
Confidentiality of communication: according to the constitution, every citizen has the right to privacy in their communication with others. The legislation also applies to e-mail and all electronic communications. Therefore, do not open e-mails addressed to other recipients without the express permission of the recipient!
Do not disrupt the operation of the data network: intentional disrupting or overloading of the data network, data transfer, e-mail and other online services is prohibited.
Hacking: intrusion into or unauthorized use of an information system – even if no damage occurs – is a criminal offence which in the worst case can lead to a jail sentence. The mere attempt of intrusion or unauthorized use is punishable.
Creating and spreading viruses: creating and deliberately spreading viruses are punishable offences.
Do not send e-mail advertising: do not use e-mail for marketing purposes unless you have permission from the recipients. It is illegal to send automated mass mail to individual persons. However, sending information to companies, your clients or friends is allowed. Even in these cases you should remove the recipient’s name from the distribution list if they so request. You can make the recipients’ names invisible to others by entering them in the bcc (Blind Carbon Copy) box.
