"Be nice" can be interpretted by the dozens of staff members any way they want. Since MD appears to the source of 95% of our hassles, I encourage the staff to be even stricter there.
So, to make sure that your post doesn't get edited, or deleted, or that the whole thread doesn't get deleted, you would need to make sure that not one staff member would find something less than nice in your post.
There have been a few people that thought it would be fun to post whatever they like and let the staff clean up after them. Naturally, I'm concerned that this wastes staff time that could otherwise be spent on helping greenhorns learn
Java. So we ban people that make a habit of being less than cooperative with the staff.
