it started a few months ago, at first I thought it was a coincidence but the similar number of downvotes always make it with no explanation for downvotes.

Now it's blatantly obvious somebody is drive by downvote manipulating my comments.

The similar number of downvotes may be explained because many users (i.e. me) don't like to downvote grey comments (unless they are very offensive or extremely wrong).

Moreover, I sometimes upvote grey comments that I don't like because they are too light grey (unless they are offensive or very wrong). I guess I'm not the only one. So this may explain that some comments stabilize in the same tone of grey.

As the other comment said, try asking the mods [e-mail]

Yeah except the timing of the downvotes are always the same, which made me think somebody is doing it on purpose.

Having said that, I believe that there is a ring of high karma accounts manipulating and censoring comments. I see regular comments that shouldn't be downvoted censored because it's critical of some startup/company that has HN users involved.

Anyways, my trust for HN is at an all time low.
