In germany its several laws. The probably most important is 305c of the BGB: if an part of an contract is not common or surprising are invalid. For example the part of the contract of bluesky where they own the posts and media you make is invalid in germany. the BGB is full of laws that limit what legal contracts can. Some limit the form (you can't sell some things without an notarized contract), while others limit who is allowed to be an contracting party (children under seven are not allowed to buy anything by themselfs and under 14 you need the explicit consent of the parents).
