You can and you should, because the collective fury of state authorities, of representatives of the economic environment and of hackers does not stop where you draw the limits and where you consciously give up communicating personal data. Even persons experienced in the technical field are frequently surprised and scared by the new connections allowed even by the smallest bits of information, because nobody is fully aware of their consequences and cannot fully imagine what you can now obtain by associating the data available, and the manner in which profiles can be drawn-up. The rasters are becoming increasingly detailed with each additional piece of information communicated - until the individual is trapped in that structure.
First rule: avoid leaving traces. Whoever wants to leave as few traces as possible on the Internet should not give up on using CyberGhost VPN. The program offers you the highest degree of anonymity when surfing the Internet and hides your identity.
Second rule: don't trust. The Internet is a modern environment and its global availability, concentrating such a high number of cultures, has led to the elimination of certain cohabitation rules considered taboo in the past. And, since nobody knows how the network will look like in ten years (for example, there might be databases accessible to everyone, where anyone can find information on the political opinions of a person or his/her inclinations), you mustn't trust every new hype and mustn't reveal your identity immediately, if not required. A negative example confirming the fact that the Internet is not concerned with the individual's privacy is Usenet, the precursor of all discussion forums, used at the beginning of the '80s by a small number of people - which doesn't mean that its recordings have disappeared. A short search on Google allows you to view 20 years-old recordings. The users at that time had no idea that search engines will one day be so powerful, and now have to watch helplessly as their personal information becomes public.
New laws might help - but usually new technologies are years ahead of the legislator, which is why people should think about their privacy on their own and set limits for all situations presenting this possibility in preparation of things to come. It's always been discussed a lot, including in public, but the novelty is that all the information is now recorded, and the personal data are stored on the long-term, can be accessed as one wishes, are in the network and can be transferred - without even knowing who uses them and to what purpose. This should be enough to warn and summon us.
Third rule: keep it clean. It might seem paranoid, but it's exactly when we are alone in the room, in front of our computer screen, and we connect anonymously, that we should refrain ourselves the most - also because the alleged security lures us into revealing personal data. Sending job applications on the Internet has become an increasingly important practice - and just as important are the checks that the human resources managers carry out online. Therefore, reveal personal information on the Internet only if such actions are inevitable and avoid creating accessible public profiles.
Because nobody can actually verify if it's really you, whenever you can, use a pseudonym that has no connection with your real name. If possible, give up on real names, because, if 100,000 persons are suddenly called Michael Meier, those really called like that are in big trouble, and you will elegantly be overlooked due to the high number of people.
