Elisabeth, I never made the mistake of underestimate your capacity of mastering your Google Search Engine, I will not begin today.
Anybody who may have take my joke seriously is the best exemple of the numerous misunderstandings that can lead to endless useless argumentations, and witches chasing.
For the rest, Tom, you had your answer, all the posts are pointing in the same direction : this is not a troll problem this is most an ego problem. One can even be more a troll than a troll without changing identify at all. So what are you doing with this? That does not count because you can identify for sure the poster?
As YdF said, it is very easy to identify a person by its post. As long as one it taking care of what it is said and how in the post. Now I have the feeling that you are not very good at this, at least concerning mine. I often have the feeling that you are trolling me in your answers, i.e., that your ego is wants to climb over my posts instead of "listening" what I am saying.
What can one do for the ego problem now? Should you ask.
Just keep silence for a while about the excitation of your ego. Observation of the emotions. Then most of the time, the level of being in ego is left behind and the real Self of the person has a chance to appear. It is a wiser level of being, in any case, to have the ego not to be the master of the situation.
Excuse me in advance, if I sound to teach. I do not want, I just want to answer your questionning as I do when myself was confronted with this questionning.
