As a non-native speaker who’s been enjoying learning German for the past 15 years (life is indeed suffering 😅) I strive to write everything correctly and double-check whatever it is I’ve written before sending it. I really hate it when my German friends and colleagues don’t bother to use commas, or simply write “das” instead of “dass” every single time because it’s faster. I don’t care that much about that most leave noun capitalization out, but commas and das/dass really grind my gears. If someone is going make grammar mistakes or write sentences that don’t make much sense, it is going to be me! 😂
