Re shadowbanning (i.e. banning a user without telling them), see the past explanations at https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que... and let me know if you still have questions. The short version is that when an account has an established history, we tell them we're banning them and why. We only shadowban when it's a spammer or a new account that we have reason to guess is a serial abuser.
This is a big problem with trying to explain these things - people mean very different things by the same words, and it leads to misunderstanding.
So far as I'm aware, no, and there are comments from dang and pg going back through the site history which argue strongly against distinguishing groups of profiles in any way.
The one possible exception is that YC founder's handles appear orange to one another at one point in time (pg discusses this in January 2013: <>>5025168 >). The feature was disabled for performance reasons.
Dang mentions the feature still being active as of a year ago: <>>31727636 >
I seem to recall a pg or dang discussion where showing this publicly created a social tension on the site, as in, one set of people distinguished from another.
dang discusses the (general lack of) secret superpowers here: <>>22767204 >, which reiterates what's in the FAQ:
HN gives three features to YC: job ads (see above) and startup launches get placed on the front page, and YC founder names are displayed to other YC alumni in orange.

Top-100 karma lands you on the leaderboard: <https://news.ycombinator.com/leaders>. That's currently 41,815+ karma. There are also no special privileges here other than occasionally being contacted by someone. (I've had inquiries about dealing with the head-trip of being on the leaderboard, and a couple of requests to boost submissions, which I forward to the moderation team).
(I'll occasionally note an egregiously-behaving account that doesn't seem to have been already banned.)
https://en.wikipedia.org/wiki/Shadow_banning
> Shadow banning, also called stealth banning, hellbanning, ghost banning, and comment ghosting, is the practice of blocking or partially blocking a user or the user's content from some areas of an online community in such a way that the ban is not readily apparent to the user, regardless of whether the action is taken by an individual or an algorithm. For example, shadow-banned comments posted to a blog or media website would be visible to the sender, but not to other users accessing the site.
This part matches shadow banning voting and is basically the same what I wrote in my previous comment just using different words:
> partially blocking a user or the user's content from some areas of an online community in such a way that the ban is not readily apparent to the user
And this part, which contradicts what you wrote in your last comment:
> More recently, the term has come to apply to alternative measures, particularly visibility measures like delisting and downranking.
