(although he rarely accepts such requests nowadays).
This is the same as saying that the admin does not consider such applications at all.
It turns out that "The Pharmacist" has a privelege for it? The admin chose him specifically and chose his application specifically.
And what about the rest of the people? Are they shit for the admin or something?
The quote above goes back to 2014 and until 2018/2019 it was impossible to change your username and the only time it happened was a famous scam case where the member was trusted because @admin changed his/her username (I don't remember the link to the case but it is related to @atriz)
So until 2019 the quote was correct but in recent years many members changed their username, some of them are unknown so if you have a logical reason or related to privacy your username will be changed
