When I tried to link my Steam account, it shows me the following message:
"This steam account is already linked to another user."

However, I don't recall ever linking my Steam account to this website.

I didn't recall either, and to my surprise I discovered I already had an account here, I really recommend seeing if you already made an account here with any other e-mail you have

maybe I connected but it was with an email possibly which I don't remember and I no longer have access

Same problem as many. I'm waiting for a solution to this problem
