Is my ユーザー名 random?

Your ユーザー名 is random. If あなた told me your password, I would just ask あなた why あなた 発言しました that.

I think it's pretty random, like my ユーザー名 on other games: Jellyumbrella, Tonipeperoni, annabanana, purpleturtlebagel, etc

No, an ランダム name would be something like this "I ate your grandma's pants" etc. If あなた told me your パスワード I'd ignore it and try to get it out of my head.

If u told me yer password, I'd b tempted to hack it! XD

i guess???
i'd probably ignore it または something

but あなた just
recycled H?

Sorry your ユーザー名 isn't ランダム it's "hgty"
And I am not interested.

Not really, あなた just used the four keys on the center 上, ページのトップへ of the keyboard .___.
