It’s fine, not particularly your fault.

It happens, people make amends and hopefully issues like this doesn’t come up again.

Radon made multiple accounts, was possibly a pedophile, manipulated others and was doing morally wrong things time and time again, he became needy and demanded attention even when we gave it to him and showed him a better path.

Biscuit made an alt most likely to start something new where he felt his main account was failing, he didn’t feel comfortable living under that name anymore. It’s easy to misjudge it but being a teenager tends to come with many questions, a vast majority of which concerning who one is as a person, many teens adopt traits from their favourite characters, some completely manifesting their inspirations and comfort characters as themselves or very closely.

Look at you for example, most of your choices regarding your character and pfp is ryuko from kill la kill. This isn’t a bad thing, just understand that not everyone is comfortable with who they are all the time. It’s safe to assume you probably take traits from ryuko or general behaviour and imbed it into your own, you may not do it deliberately but it still can and plausibly has happened already.
