Not sure if I should go <sarcasm>That new logo design is a bit too minimal for my taste.</sarcasm> or rather opt in for a meme. – Jokes aside, it’s indeed not as it should be.

Oh, almost forgot. The “Do Rabin Fingerprints have any advantages over CRC?” Q&A would represent an equal counterexample (it even mentions the same paper you mentioned in your answer).

Besides, the paper you link to in your counterexample itself draws a clear line between cyclic redundancy codes (CRC) used for non-cryptographic detection of information errors (which the CRC tag would hint at) and the proposed Cryptographic CRC (where design goals are very different from what ye average, non-cryptographic CRC offers).

I see your point, but I’m not really sure if the fact that things like “The standard way to make a MAC out of a CRC…” is worth adding a CRC tag. I’ld argue it would be more fitting to use the mac tag in that case, as that’s what you’re effectively creating there. From a CRC tag, I – as a user, not a mod – would expect Q&As about CRCs; like: how do I create them, how do I use them, and how they are used (in a pure, unmodified way) in cryptography. I don’t think that’s the message we want to send to users – as we’ld be bound to get CRC Qs which conflict what our help center says.

@Q-Club That’s a magic unicorn handled by SE employees. We do have (read only) access to a kind of “User Vote History” though, in case something feels fishy and we want to check on it before deciding to forward an according message to the SE team. But personally, I had little reason to look at it during the past few years. If something indeed seems fishy related to votes, it’ll end up with SE employees who’ll be digging in deeper.

@Braiam Also, moderators will not undo single delete votes dropped by one or more users either. (Just in case you wanted to know about that too.)

@Braiam Unless there's good reason to undelete answers — which is not the case in 99.9% of the time — mods do not undelete answers which have been deleted as the result of delete votes by the community. Remembering the few times mods undeleted a community-voted-to-delete answer within the past couple of years, it was mostly done after a related meta discussion, which clarified the community consensus on some special case. So, in the end, such undeletion was decided by the community; the mod merely clicked the button after the majority of the community decided that that's what should be done.

@MaartenBodewes Yep. Thank [enter-favorite-deity-here] we're not SO when it comes to that. Anyway, all that stuff is something mods can't (and shouldn't) influence. Mods exist to put out fires and to help when needed, the rest is "democracy" in the hand of voting users (read: community dynamics — with all the ups and downs that tend to come with it).

@forest Nice to notice you successfully connected those dots. ;)

@forest Trying to answer all your points on a single comment: (1) Heavily downvoted As get less focus when reaching (I think) -5 votes and are faded out accordingly (example answer) to keep the appearance of the site clean. (2) Vote fraud triggering is more of an issue in cases where a single user drops many votes on a single user's Q&As. It doesn't tend to kick in when a dozen of users downvote a single A because it's incorrect/bad/whatever. (3) Answerers getting many downvotes should enhance their answer (or delete it if they prefer that).
