It seems Jotaro's message here was typed like a creepy middle-aged man's chat message in Japanese (except without the excessive emoji usage). This style is known as "Ojisan koubun"/おじさん構文 or "ojisan-gokko". The latter is for when the participants are pretending to be old men hitting on younger women.
