The "Are We Dating the Same Guy" groups on Reddit and Facebook are private or semi-private groups typically for women, where members share information about men they are dating or have dated, often to warn each other about potential red flags or problematic behavior. These groups originated as a way to protect women by sharing knowledge about serial cheaters, abusers, or men with a history of dishonest behavior, but they can sometimes be controversial. Some members find these groups useful for screening dates and learning about men's past behavior from other women. However, others note that the groups can include a lot of speculation, harsh judgments, and sometimes inaccurate or unfair comments, which can lead to false accusations and feelings of harassment for men posted there. The dynamics can be emotionally charged and cause harm if not properly moderated. The groups are known to operate under strict rules in some cases, and an official site related to the concept (arewedatingthesameguy.com) tries to manage fairness for all parties. But criticism remains about the potential for misuse, privacy concerns, and the emotional toll on men who get posted about. Overall, these groups are a mixed phenomenon with both protective intentions and potential negative consequences, and opinions on them vary widely among users on Reddit and elsewhere.
