His/Her name is hj93, I accidentally removed him from my league and now I’m not sure how to reach out to him. I am using the demo version of lfs so I can not contact him through lfs and I couldn’t find any social media either the same name, if anyone has an idea on how to message him or re add him please let me know how.

Go to LFSWorld.net, open the 'LFS Racers Database' window and find your team in the 'Search LFS Teams' tab.

There should be an edit button next to the name, click that for the page where you can add people to the team.

Thanks! If I add him back into the league will he get notified?

Not sure.

Demo accounts can not sent private messages because it could be abused for spam.
I sent hj93 a private message with title "IncogSalmon wants to contact you" and a link to this thread.

You could also watch at https://www.lfsworld.net/?win=stats&racer=hj93 when he comes online and join the same server.
He last raced online today a few hours ago.
