Meldou, also known as Alex, is a relatively active user on the infamous sub-form Off Topic.
Meldou's posts mostly consist of responses and are generally helpful and or jokeful banter. He is commonly though to be Meldo due to his username, but has stated on many occasions that he is simply an admirer. Meldou is not a very active OTer which is similar to the actions of Meldo, which is maybe another reason why the two are viewed as the same user.
He is usually seen wearing the ROBLOXian hat titled "Punk Kid".
He has rarely used the package ROBLOXian 2.0.
It is possible Meldou does not care too much about his appearance.
