tecteem.comRe 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.
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).
