You can ask the admin politely on his/her wall here to lift the block, but they don't have to comply with that.

Since it's only three days, I would advise you to just sit it out. Actually, there is an appeal process only if you ask the admin to unblock you. This can only be if you haven't broke their rules and made improvements to anything. Admins only block people if they break the rules or if they break the terms of use.
