我猜着你的名字刻在了墙上我画了你的摸样对着弯月亮

This net name seems poetic and imaginative, possibly implying someone who deeply cares for another person. 'I guessed your name was carved on the wall' is likely a metaphor that one's feelings are as solid as carvings, and it's an expression of admiration or adoration. It suggests that despite not knowing exactly what to call the admired person, he or she still creates an artistic depiction under the crescent moon - this alludes both longing in solitude and romantic idealization.
