You can't use the services until you confirm the account via email. When you sign up, you provide and email address, and the you're presented with this:
"You've successfully signed up. Please check your email to confirm your account before signing in to the Supabase dashboard. The confirmation link expires in 10 minutes."
If you attempt to sign in before verifying, you'll see:
"Account has not been verified, please check the link sent to your email"
So nothing is going to happen. This is probably a bot probing for accounts. The system is operating as intended. No cause for concern.

One more bit: when you receive the initial account email, you'll find a note at the bottom confirming the intention:
"If you didn't request for this, you can safely ignore this email."
