When I started out on my path, there was no such thing as cyberspace. Psychic attacks (such as they were) existed in the here and now, amongst people you often knew or recognised.
Nowadays it is quite different. Cyberspace gives us a chance to do some pretty spectacular magical journeying. We can be whoever we want - change gender, change our age, change our looks, invent a whole new look. Our avatars may look nothing like us. (Ahem - mine certainly looks nothing like me, I hope! 
)
But there are some risks. Magical journeying without a computer takes skill, some training and is vastly tiring. Even so, people years ago recognised the risks - describing someone as 'away with the fairies' could often mean that they had spent too long in Other Worlds, making it difficult for them to adjust to reality, and making them vulnerable when they tried.
The same goes for cyberspace. I'm amazed just how long each day some people spend in this 'Other World.' Probably longer than they do in the real world. And yet the same problems apply just as they did years ago - being 'away with the fairies' makes it hard for us to get back into the real world, and it weakens us too, making us more vulnerable to psychic attack.
And of course, there are psychic attackers out there. The sheer ease of slipping into this Other World is extremely tempting for those who would like to exercise a bit of psychic muscle. They prowl around, looking for their victims, and can do just as much (some would say even more!) damage as an ordinary attacker.
Psychic self defence in cyberspace is very like ordinary psychic self defence. You need to avoid your attacker by not visiting sites or pages that they frequent. You need to learn to shield yourself (psychic armour is still useful in cyberspace) and block all communications with them.
Remember that in this Other World, the ordinary rules we are used to have twisted somewhat. You are not on a level playing field. Your attacker will pick their ground, and you must likewise find a good defensive position.
But, most important of all with these cyber-attacks, you need to ground yourself (get off-line a bit more!)
