Check the provenance, not just the link. Before you click, look for where the URL came from — trusted community posts, long-standing directories, or reputable researchers are safer signals than random forums or DMs. Cross-reference the address with multiple independent sources; a single mention is not proof of legitimacy.
Watch for lookalikes and tiny typos. Scammers rely on visually similar URLs and slight misspellings to trick people. If a link looks “off” (odd characters, extra words, or unexpected redirects) treat it as suspicious. When in doubt, don’t follow it and verify the address elsewhere.
Keep personal data out of the URL flow. Never paste or transmit usernames, email addresses, phone numbers, or identifying details into web forms reached from unknown links. Even small bits of personal data can be harvested and re-used — the safest habit is to avoid sharing anything sensitive at all.
Favor reputation over flashy claims. A long vendor or site history, consistent user feedback, and community confirmation matter far more than bold promises or “too good to be true” listings. Look for patterns of consistent behavior across time — one-off endorsements or glowing claims with no context are red flags.
Know the legal and safety tradeoffs. URLs can be gateways to scams, malware, or illegal activity; understanding that risk is more important than chasing novelty. If you’re researching for education or journalism, stick to reputable reporting and archival sources; if you suspect criminal activity, the safest course is to disengage and, when appropriate, report it to authorities.
