Be aware of catfishes on dating websites. According to WebMD, a "catfish is a term for a person who pretends to be someone else online. A catfish uses fake photos, and sometimes a false persona, to find friends or romantic partners on the internet."
Avoid giving out personal information. If you're communicating with someone who attempts to pressure you into giving personal information such as financial information, stop communicating right away.
If you decide to do real-life meetups, always be cautious. Tell friends your whereabouts. Choose a public location for meetups.
