After Massachusetts resident Kathy Brown saw photos of another Boston Marathon runner wearing her same number, she realized she’d caught a “bandit,” the nickname for an unregistered runner. Even more interesting was that the runner is wife of Dennis Crowley, co-founder and CEO of the location-sharing app called Foursquare. Chelsa Crowley was not hesitant to advertise through her social media accounts that she was running in the marathon last Monday, despite not having actually registered.

The couple has issued an apology since it was revealed she used a fake bib to run. Despite the apology, fellow runners have taken to Twitter, Instagram, and Facebook to share their opinions about her actions, many using the hashtag #bibgate as well as announcing they would be deleting their Foursquare accounts because of the incident. Most of the comments focused on doing something so disrespectful one year after the bombings. While a number of people are caught using fake bibs each year, they often do not have the same status as the Crowleys, who married last fall.

“It’s clear that both Chelsa and I lost perspective on how our actions could be hurtful to others. What we did was wrong and we’re sorry. Our biggest regret is that our actions have overshadowed the event for those who ran and ran to honor others,” he wrote in a statement on Medium. “I grew up right outside Boston and this race means so much to me and my family. Chelsa and I are going to work to make this right, but out of the public eye. The Boston Marathon is about something much bigger than us, and we appreciate the reminder.”

Several of those who commented on social media said it was difficult to take the apology seriously because even after she was found out, Chelsa went on to post a photo on Instagram of herself with the caption, “Heading to DC for Nike Women’s Half Marathon and strategizing on how to even out my tan lines from #Boston.” On the day of the Boston Marathon, several people questioned whether or not her bib was fake, and Chelsa wrote back on Twitter, saying, “shh!!” It hardly seemed as if the couple was trying to conceal their actions.

There were also those who didn’t think Chelsa using a fake bib was a big deal. The couple ran the marathon last year and were separated for some time after the bombs went off—an experience Dennis wrote about on Medium. While Chelsa finished the race in 2013, Dennis did not, which meant he was immediately given a number this year. After several failed attempts at getting her a number this year, the couple decided to go ahead with the fake bib.

“We both felt like we needed to run again and finish together to get closure,” he said, according to The New York Times Blog.
