As with everything there's a time and a place. This was the guys first post on the forum and it was in the New Member Introductions area. Out of the first 11 replies there wasn't a single post with a welcome in it, in fact there was only the first reply that was actually addressed directly at him, the rest were just other members having a discussion between between themselves about him and/or his supposed lack of qualifications.
This forum is open and equally available for anyone working in the electrical industry, there's never been a minimum qualification requirement. You're free to pick and choose which threads you post on and which members you interact with but there's going to be moderation whenever threads go the general direction of making someone feel unwelcome and excluded so maybe just avoid threads where the trend is becoming exclusionary and your post may become collateral damage. I don't have the time nor the inclination to edit posts line by line, remove quotes of deleted posts to try and make the thread readable after moderation so in this case it was easier to just delete the lot and start again. If you feel the moderation is excessive or too severe, too broad, inconsistent, misguided or unfairly targeted you're welcome to take issue with Dan. Calling the staff Nazis or Stazi is exactly the same mentality that's causing the original posts to be deleted.
