Just out of curiosity, what sort of answer are you expecting? Your post reads as vaguely accusatory to me - like you're implying that messes are being left intentionally

Accounting for their username they are either making a joke or trying to assess the potential performance of the strategy even if they get flagged.

Shills don't care about their accounts, just that they spray their message around. Just curious if the silent system works fast enough.

For my curiosity, by the way, my account was rate limited. Thanks Dang.

Your account was likely rate limited because you decided to make a new account here, and new accounts have severe limitations on rate of posting comments. You could have just as easily decided to use your existing account and would've been fine.

As Operyl correctly said, your account was rate limited because new accounts are subject to rate limits.

Btw, could you please not create accounts for every few comments you post? This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html.

You needn't use your real name, of course, but for HN to be a community, users need some identity for other users to relate to. Otherwise we may as well have no usernames and no community, and that would be a different kind of forum. https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme...

I never look at the name of the user posting a comment, just at the comment's content. Do people really remember names here? Just such as mine?)

Yep. And have posted a couple of times suggesting mild enhancements for those of us that do. I believe there are plug-in or extension type reader thingymabobs that help with that too.

Your name, alas, is not human-memorable. See also - https://xkcd.com/936/

Ah, I see, could you try asking in a more neutral fashion in the future? I've noticed the last couple years that a lot of potentially interesting or valid criticism sabotages itself with weak implications of conspiracy followed by accusations of persecution.

Turn on showdead -- sometimes they last until the user/human-in-the-loop notices that they've been hellbanned.

I'm not sure I understand your question. Sometimes they get "taken care of" instantly by software. Sometimes it takes moderators minutes or hours to see them and "take care of" them. Other times we don't see it and an email from a user asks us to look into it, which we do. That can take a bit longer because there's an extra hop in the path.
