What types of scams are common on Reddit (crypto, giveaways, phishing)?

Reddit hosts a variety of scam patterns that target users across different communities, and recognizing the common formats is the most effective defense. Most scams on Reddit exploit the platform's reputation as an authentic, peer-driven community by attempting to blend in with genuine user content or conversations. Cryptocurrency scams are among the most prevalent. The standard format is a post or comment that presents a fake giveaway — typically claiming that a celebrity, brand, or crypto project is distributing tokens or coins to anyone who sends a small amount first to "verify their wallet." This is an advance-fee fraud structure: you send a small amount and receive nothing, or your wallet address is used to drain your holdings through a malicious contract interaction. No legitimate cryptocurrency giveaway ever requires you to send crypto first. Fake customer service impersonation is another common pattern. After you post a question or complaint about a service in a relevant subreddit, accounts impersonating that company's support team will contact you by direct message offering to help. They then ask for account credentials, two-factor codes, or payment information. Legitimate company support operates through official channels, not through Reddit DMs initiated after you post publicly. Phishing links appear in DMs and sometimes in comments, often disguised as surveys, exclusive content, or platform verification requests. The links lead to credential-harvesting pages that mimic Reddit's login screen or other services. A link in a DM that asks you to log in or confirm your account details is almost universally a phishing attempt. Romance and investment scams, sometimes called "pig butchering," occur in communities focused on investing or personal finance. These involve extended relationship-building before eventually steering the target toward a fraudulent investment platform that shows fake profits until the victim attempts to withdraw.
