I have often seen the removal of phrases like "thank you" that mostly newer users, especially 1-rep users, tend to append to their questions.

I even do this myself, mostly because it seems to be a common standard here. I have a speculation why this is done, but want your opinions or a specific reason for it.

In addition: How to justify the changes (in front of the new user) when the main part of the edit is the removal of the "thank you"?
