that's true.Maybe you can ask them to write in standard malay language.

Learning from Malay youths on social network is the worst way of learning the language. 1. Generally, we speak in dialects (Northern Malay, Kelatanese Malay etc.) 2. The grammar used is only for informal usage. They are actually all grammatical errors as the correct grammar is kinda troublesome. 3. Shortforms. Many shortforms used are unofficial. It's created by youths. Sort of like text messaging and internet language.
