No court has ruled on the validity of the ESAs in general; Decisions are limited to certain provisions and conditions. Several companies have parodied this belief that users don`t read end-user license agreements by adding unusual clauses, knowing that few users will ever read them. Aprilscherz added a clause according to which users who placed an order on April 1, 2010 agreed to irrevocably give their soul to the company, which 7500 users accepted.

The PC Pitstop program contained a clause in its end-user license agreement that states that anyone who reads the clause and contacts the company receives a financial reward, but it took four months and more than 3,000 software downloads before anyone collected it.  When installing version 4 of the Advanced Query Tool, the installer measured the time between release and acceptance of end-user license agreements to calculate the average read speed. . . .
