block.siは安全ですか？

i don't like that it blocks off too much including the sites that are NOT inappropriate. i think you should disable it for at least a month and fix ***** also blocks off to many games and teachers struggle trying to fix that but they can't seem to.if you can unblock games sites such as all unblocked games, kizi, crash drive 2,cool math,agames,and other games like them.i would really appreciate it.and i'm not saying you did not do a good job with it you just need to make some changes.thanks for understanding!
