I don't think these comments deserve downvotes, and normally it's unlikely to get three consecutive "-8"'s (several days ago there was no downvote). So my conclusion is that some toxic users just gathered here and deliberately downvoted things. Maybe it is this post attracting them.
I don't care about contributions now, but I want to let everyone know this disgusting conduct. Also I think for the website it's good to show who did upvotes/downvotes. Life is not only about algorithms, but also about how to respect others (even when you are anonymous).
[Update] It seems that high-rated users have high-weights. This might make sense on algorithm discussions.
one time, I downvoted some comment on some old blog, and it got -8. It may be related to this:

Assigning high voting-weights to high-rated users only makes sense on algorithmic discussions. Still, even in such discussions there could be personal bias. I believe the only solution is to show voters' names.
Deleted.
Can relate so much, I have been experiencing that cursed $$$-8$$$ for a few months already. My contribution's been recovering recently and that's good, but I have been bothered more on the consistent $$$-8$$$ than the contribution loss so far.
Same here (!-!)

A -8 is a downvote by a single master. Usually the reason for downvotes is just you made too many comments under one blog (given your comments). I'm not going to claim its good or bad, but it's pattern I've seen.
oh
Let's keep downvoting this person
Let's keep downvoting you also :)
