Yeah, I'm a professional copy editor/copyeditor. (Pick one, they're both acceptable.)
If I'm not being paid, I don't worry about my writing. I use internet-register American English quite often. I comprehend meme-speak.
Sometimes I even drop a word. If I notice, I go back and fix it. If I don't. c'est la guerre.
Same for other people's writing. You want corrections? Pay me. Otherwise, I couldn't care less. If I don't understand, I'll ask. If I can figure it out (maybe you hit a key next to the one you really wanted), I keep quiet.
IF by chance I know the person, I might DM them. If they're a stranger, no. (I have my DMs locked to keep the randos out. I know I'm not alone there.)
The Golden Rule appears in multiple cultures worldwide because it's common sense and it's kind.
Treat others as you would have them treat you.
Enjoy the rest of your weekend, folks.
