SMS is bad for for standard english do you agree?

If you ask me i can tell you i totally agree! I can give you an example one day when my sister was playing maple story,she keeps on using shorcuts...Somesay...hu r u?is it much easier to understand if you type who are you?so i 100% agree that SMSes language are bad for english! For my second reason sms language may affect your exam if you suddenly forget you are doing your exams whta will happen if you type Tom wad do you wan?instead of Tom what do you want?This will affect your english marks,so NEVER EVER NEVER EVER use SMS language!
