Contact the editor, author or project manager and ask them for guidance.
If the original author decided to quote the exact message/style, not sure why you shouldn't but again your safest bet is to ask. Ask yourself: What did the original author want to achieve by maintaining the original internet-message style, and when you know the answer, achieve the same thing in your translation using any method needed.
Ask the author and if he/she needs advice search what other authors have done under similar circumstances.
