account is under review ?

hi. i registered linode and find it a bit hard to setup because i haven't any linux experience. so i deleted my account completely. but then i decided to come back and learn linux and setup linode server. but when i registered second time with same email it says "account is under review". but first time it didn't say this.instead, i directly started setup server without any waitings. why this happened now ? why it says account is under review ? because i registered twice ? and is it possible to start setup server immediately ? sorry for bad english
