I’ve only skimmed your comments, but I think a factor is also that a lot of them are really hard to read.
Examples I see are weird sentence structure, the lack of paragraphs for longer messages, the lack of capitalisation, and rather odd/hyperbolic use of words (writing in the same way you’d speak?). This “style” just gets interpreted as “noise” when I’m reading it, which will get downvoted as it doesn’t contribute.
English isn’t my first language either (it’s not even my second or third!) so I understand it’s very hard to get these things right. But without sufficient clarity you will get downvotes, as it just comes off as noise.
