On Sunday, an investor and influencer told people to knock on doors to boost career connections — and frustrated the internet, Fortune reported Wednesday.

Public-safety experts told Insider it might not be the safest idea ever, depending on how you do it.

On Sunday, Sahil Bloom, managing partner of SRB Ventures, advised young people who are trying to "get ahead" to don a button-down shirt, bring a jug of coffee and cups to offer, and knock on the doors to ask people for career advice

Twitter users responded strongly to the thread, as Fortune noted. "Can you imagine trying to do this if you're black," one user quote-tweeted.

"Hustle and grind guys are always like 'my best advice is to inconvenience and annoy as many people as possible,'" another person tweeted.

Bloom acknowledged the reactions in follow-up tweets and in an emailed statement to Insider. (He also said he thinks of himself as someone who tries to help people move away from "hustle culture.")

"I didn't think through all of the challenges and nuance very well before sharing it — fully accept all of those pushbacks and disagreements and learned a lot from it," he wrote to Insider.

He added he was inspired by a conversation he had with a musician Saturday who knocked on his door, and Bloom later helped him film a music video. "It was admittedly naive to think that everyone would have an experience similar to this young man who came to my house," he added.

Public-safety experts had mixed reactions to Bloom's original advice.

"From a crime-prevention standpoint, I would caution people from doing that," said Brent Ambuehl, crime-prevention coordinator at the El Paso County, Colorado, Sheriff's Office.

Alicia D. Smith said she thought Bloom's idea was cool — with caveats. "I would totally do that. I totally would. I think if a person knows their community," it can make sense, Smith said.
