No one reads the terms of service. Lawmakers want to fix that with 'TLDR' bill
Don't bother. Just ban/declare invalid any surprising clauses, with a regularly updated list of prohibited abusive terms that people try to slip in.<p>Germany has an explicit rule like that (§ 305c BGB): terms that are so unusual that the counterparty didn't have to expect them are null and void, and any ambiguities are interpreted against the side using reusable T&C's. Terms are further invalid (§ 307 BGB) if they unfairly disadvantage the other party against good faith etc.<p>The real meat starts in 308 and following, explicitly banning many terms - for example arbitration requirements (309 item 14).
