I don't.
Why titled players use his own name and we other, use nick names, as chess.com accont user?

Chess.com pays them to use use their names. So they can say "Look everybody! Your favorite player plays on our site!!"
Lichess and ICC pay better though. Which is why they have more.

The site doesn't pay titled players to use their names. There are plenty here that don't, but the site does require the real name to at least be on the profile for some types of events

Hmm... is it just me, or did ICC lose a lot of members to Lichess and chess.com in the last couple of years? It seems that there aren't as many players in the pool these days...

doesn't everyone use there real names like me
I like to use my nickname, no worries, its my official nickname, everyone calls me that a home too, "Ron" but not my real name =)
