In the hours following the San Bernardino mass shooting that killed at least 14, a hashtag chronicling the developing story began trending on Twitter. The only problem? It was misspelled.

What should have been a hashtag of #SanBernardino became #SanBernadino.

The incorrect hashtag has now been used more than 333,000 times, according to Twitter.

The misspelling offended some who said it showed a lack of respect for the city. San Bernardino is the poorest city of its size in California and in its fourth year of bankruptcy. The Times recently wrote a series about the troubled city.

Shows you the quality of thoughtful, intelligent dialogue on Twitter when the trending hashtag is MISSPELLED #SanBernadino vs #SanBernardino — Doug (@omarspeck) December 2, 2015

Ok, #1 trending Twitter topic is #SanBernadino.... It's #SanBernardino. The least you can do is respect the spelling of city of tragedy. ¿¿¿¿ — Shawna Alpdemir (@Shawna_Alpdemir) December 2, 2015

I am herewith blocking anyone who cannot give San BernaRdino the dignity of spelling the city's name properly #ccot #tcot — Papa Dog (@eclectichorzman) December 2, 2015

Lots of concern for the imaginary city of San Bernadino?? Maybe spell it right?? Kind of insulting https://t.co/qmwlRZmM7U — Jon Cupo (@joncupo) December 2, 2015

Others in search of information on the shooting were frustrated that the misspelling kept them from finding the hashtag.

#sanbernadino - can we just all spell the name #sanbernardino correctly please so that info is easier to find - jeez. — Brenda (@ffs_just_stop) December 2, 2015

When you realize the #SanBernardino feed is slow because misspelled #SanBernadino is what's trending. Ugh. — Lynda Waddington (@LyndaIowa) December 2, 2015

Many news organizations noted the misspelling and some chose to use the correct hashtag instead. NPR’s main account tweeted that the organization would be using the correctly spelled hashtag after realizing the error.
