joking aside, it looks like he's using a translator. all of his posts are hard to read.
What I don't understand are the punctuation marks and the multiple full stops. What kind of crappy software provides such results? On a phone, the full stop is right next to the spacebar button. He might be typing it manually. But someone with such limited English language skills would surely make spelling mistakes as well, however, there are none in his posts. Spellcheck and Grammarly would surely fix that.
now that you mention
spell check and Grammarly, I think you're right. my phone does have a spell check feature. seeing that the period button(which I always accidentally push every time I type on my phone) is right next to the space bar on phones, it's probably the most likely scenario. I completely forgot about the spell check that's why I thought of a translator.
