Is that what is happening? I was struggling to see a possible reason for why your post was being voted down, and unless your original post was modified, there are not many other explanations (unless people don't understand how gravity/orbits work).

I would be very disappointed if members of the HN community are voting down your posts because of who you are, rather than the content. I'd like to think we're above that sort of petty behaviour. If it were were moderators abusing their positions...

Yeah I have no idea why your parent post got down voted. Why do you say HN mods downvote you?
