People all around the server do so. Noone is sanctioned yet. I can go presetengage on almost any of my characters and won't get sanctioned and that's just how one can make some proper use of his set of ID rules.
My first meeting with Wilde was with Vrabcek on his Hans Echkard, while I was in Rheinland Federal Police faction. It was my first serious experience and I failed dramatically, I think. I also accidentally shot him when his Wraith was targeted instead of NPCs flying around. Yet he left me leave, yet we met again later, but it doesn't matter, you asked about the first experience.
People remember their experience with the others. If one went engabung or "**** NOMAD" (true story) first, he shouldn't complain when getting shot.
Most of the times people whine they whine because someone did to them what they do to the others. I don't know if that is relevant to your experience, but it's totally relevant for the original poster and was mentioned by every second player in this thread.
