Alex Rosen (also known under his online aliases Chet Goldstein and Gordon Flowers) is the founder of Houston-based vigilante organization Predator Poachers, which conducts sting operations on adults who seek sexual activities with minors. By 2023, the organization has claimed responsibility for arrests in 46 U.S. states and convictions in 33, though this statistic has not been fully verified.^[1][2]

Rosen founded Predator Poachers at the age of 19 in his hometown of Houston, Texas.^[3] The operations conducted by the group generally follow the strategy of creating a fake account on a dating app, waiting for an adult to message the account and then quickly disclosing that the account in question belongs to an underage person. If the target continues to message the account, the chat is then usually followed by a staged, real-life meeting with the suspect.^[4][5][6] "We drop our age immediately. We don't give them any doubts as to how old we are," Rosen stated in an interview with Fox 40.^[7] The organization is funded by membership subscriptions and merchandise sales on its website.^[4]

Most of Predator Poachers' operations take place on Grindr, an LGBT online dating application. Grindr became closely associated with Predator Poachers' brand on its YouTube channel, whose banner featured an illustration of a smartphone displaying a Grindr conversation. In an interview with The Verge, Rosen stated that the reason why "we use Grindr as number one is because... I didn't have pictures of underage girls on my phone," he told the organization. "I do have a little brother though, and I did have pictures of him on my phone."^[4] Rosen told the Insider that, in a 2021 operation, he had used his 16-year-old cousin as a decoy, adding that he agreed that "it was very irresponsible."^[8]

A 2020 article by Cincinnati CityBeat stated that, in many videos, Rosen seemed "to instigate fights, or use excessive profanity and derogatory terms", and that the language he had used on video resulted in his YouTube channel receiving two strikes.^[9] The channel was later banned from the platform due to receiving multiple community guidelines strikes. Another channel he created on the platform was deleted in 2021.^[8]

When asked about the opinion of law-enforcement officials who say that such matter should be left to police departments, Rosen said that "every single department is either going to say nothing or discourage it publicly, but we've seen that departments that discourage it publicly will work to prosecute our cases". Upon being interviewed by the St. Louis Post-Dispatch about the topic in 2019, some law-enforcement officers stated that the phenomenon of predator hunters can create a new form of mob justice and engineer chaotic situations that should be left to professionals.^[10]

On July 24, 2024, Rosen stated that a 60-year-old man had died by suicide after Rosen and his team accused him of viewing child pornography. According to court documents, the man, Donald Anthony Letcher had been previously accused of child molestation in the 1990s in a criminal case that was ultimately dismissed by the prosecution after the South Dakota Supreme Court overturned the man's conviction due to concerns regarding the credibility of the witnesses and another evidence-related issue that, the court stated, "severely prejudiced [his] ability to defend" himself. Rosen and his team were detained by police during the incident.^[11]

Rosen has described himself as "very, very right-wing", as a Libertarian and as a Conservative. He runs a 450,000 followers account on X (formerly known as Twitter).^[12][1]

In June 2023, Rosen confronted COVID-19 expert Peter Hotez at home in Houston. The visit happened after Hotez declined to debate presidential candidate and anti-vaccine activist Robert F. Kennedy Jr. on the Joe Rogan Experience podcast. During the encounter, which happened at the sidewalk of Hotez's home, Rosen asked Hotez why he had refused to debate Kennedy and whether he believed in "vaccine injuries". Hotez responded that he was still considering debating Kennedy and said "don't come to my house" before going back inside. Later that day, Hotez stated on social media that he was "stalked in front of my home by a couple of antivaxers taunting me to debate RFK Jr."^[12][13]

Rosen has made negative statements against LGBT and transgender people. According to Texas Observer reporter Steven Monacelli, Rosen has described the LGBT community as a "cult".^[2] In a social-media post published prior to March 2020, Rosen called his followers to help cancel a drag queen story hour event at an Idaho library. "I don't think that shit needs to be around kids, because kids are kids. They can't decide what their preferences are at that young age," he stated when asked about the post.^[4]

Rosen has repeatedly used racist epithets at the men that he meets in his sting operations.^[4] In 2019, Rosen used a racial slur on video, an event that he later confirmed in a 2023 interview with the Evansville Courier & Press. In the interview, in which the news organization asked him about his previous use of racial slurs, Rosen stated that he is Jewish and that "I said it, but I'm not apologizing for it. Because, you know, people say that word has power. I mean, I don't think making Holocaust or Jew jokes has any power."^[14]

Rosen has said the n-word in multiple YouTube videos and livestreams. In a prank call to a Black Lives Matter hotline, he used multiple homophobic and racist slurs. Rosen stated in an interview that "it obviously looks bad" and that he had "no hatred in my heart towards any group of people".^[8]

Amid an early 2025 anti-immigration backlash against Indian H-1B workers in the United States, Rosen published a video on X in which he visited Indian-owned shops and urged ethnic Indians to sign a mock petition to stop "the spread of the H-1B virus." Rosen stated on social media that the metaphorical virus "originated from India" and its "symptoms" included "smell" and "diarrhea", adding that it was the "deadliest virus" in the country. The video garnered over a million views and was described as racist by many users on the platform, although other users supported Rosen's actions.^[15][16][17]

Previously, in June 2022, Rosen published a video of himself confronting Republican representative Dan Crenshaw at the Texas State Republican Convention, calling him a "World Economic Forum sell-out", until being stopped by security.^{[12][18][19][20]} In October of the same year, Rosen posted a video where Harris County officers told him that he had been banned from the Harris County Commissioners Court for being "disruptive".^[12]

In October 2023, Rosen heckled 2016 presidential candidate Hillary Clinton at a Houston rally and accused her husband, Bill Clinton, of having visited Jeffrey Epstein's island "26 times". He was subsequently dragged out of the event by security.^[21][22][23]
