As you can see I made an edit but it won't stick and gets deleted right away; another user with 20k rep also tried to make the same edit with no luck.
This is the answer where it happened. Also I have copied it to the answers in this question; feel free to try and edit it by adding Hair, to the front.
Hair,
You can get a temporary workaround by adding an invisible comment using <!-- --> at the beginning of your answer. Then you can add 'Hair' after it. I agree though that this needs to be fixed.
We have performed a Hair removal removal. Having said that:

Hair is no longer trimmed, cut, stripped, or buzzed.
Considering the regex used seems to be:
^ # begins at start of body
\s* # possible spaces
(
hii?(?![a-z])| # any of these greeting words
hello|
h(e|a)y(?![a-z])|
dear|
greetings|
hai|
guys|
howdy|
h(i|e)ya|
hola
)
.*? # followed by anything, up to...
(
[.,;!-]+ # one or more bits of punctuation
\s* # possible spaces
|
(\r?\n)+ # one or more newlines
)
Replacing the .*? by something that matches less should fix it. My suggestions:
(\W.*?)? makes sure that any of the bad words is followed by a non-word character before matching anything else\b.*? makes sure we're at a word boundary before matching the restPutting it together and removing superfluous bits
^ # begins at start of body
\s* # possible spaces
( # any of the following greeting words
h[ai]i?|
hello|
h[eai]ya?|
dear|
greetings|
hai|
guys|
howdy|
hola
)
\b # word boundary, to not match words that begin with a bad word
.*? # followed by anything, up to...
(
[.,;!-]+ # one or more bits of punctuation
\s* # possible spaces
|
[\r\n]+ # one or more newlines
)
Of course, you should check this against your unit tests. You do use unit tests, don't you?
And this would still match a useful answer on [workplace.se] that reads
Greetings should be exchanged as soon as you enter the room for your interview.
or
Dear or howdy is much too informal for a letter to a supplier.
or, over on [musicfans.se]
Guys 'n' Dolls is probably the band you're looking for.
So I agree that a pop-up alerting the user might be better.
The icy ball form of precipitation - induce the same bug.
The regex is attempting to defeat an initial "hai" (as in o hai), but it is overzealous.
The regex being:
^ # begins at start of body
\s* # possible spaces
(
hii?(?![a-z])| # any of these greeting words
hello|
h(e|a)y(?![a-z])|
dear|
greetings|
hai|
guys|
howdy|
h(i|e)ya|
hola
)
.*? # followed by anything, up to...
(
[.,;!-]+ # one or more bits of punctuation
\s* # possible spaces
|
(\r?\n)+ # one or more newlines
)
/usr/share/dict/words, the only problematic entry is hai, which matches a variety of "hail" and "hair" words (plus "Haiti" and "Haitian"). dear matches a few, but they're all uncommon or are derivatives of "dear" such as "dearest". Nothing else generates false positives.
hai is again the main problem one, although hola generates a fair few false positives as well. dear and hello generate a bunch of hits, but they're almost all titles in the form of greetings, except for variations on "Dearborn".
hay, in a hypothetical answer on the bio stack, on what to feed cows?

Hair, and particularly facial hair, is a sort of defense. It's harder to take a bite of someone's throat, or scratch their throat if it's covered in hair.
So in a jungle setting there can be predators that prey on humans, but if they have longer facial hair they will be more likely to survive.

Granted this doesn't depend on how fast it is, so an additional thing could be that there is a micro organism that feeds of dead cells (which includes hair) so it is impossible to grow a beard very long because it gets all eaten after a certain amount of time. In this case the faster that the hair grows the longer the beard can be and thus the more protection it offers the person and thus increases their chance of survival.
