I have noticed this about Sylvette as well. The only time I ever see him post is when he has the opportunity to create some type of disruption and has the chance to bait people. Just like this response to my post that has nothing to do with healing, the forum or the topic:
Has anyone ever written you , that you have a really dumb-looking avatar ?
It is obvious he is baiting so he can create some sort of disturbance. No wonder he has been banned so many times from CZ. But again the moderators or webmasters let him get away with his antics too long just allowing the troll to feed and get stronger.
