There is a group of people who love doing this and there are many of them, in general I don't care - if they like doing it, then let them do it, but it irritates me to try to understand who is who, moreover, they know my nickname and are in a more advantageous position.
The solution would be to display a list of all the player's nicknames if you hover over it with the cursor, and not use the !whois command, which does not even show the entire history of nickname changes.
Also, by nickname you can evaluate how a player plays, what main meta he uses, the one who changed his nickname is now unknown (until you determine who it is), and he knows how you play, because you did not change your nickname.
