You are entirely right to be protective, which is why I did a ton of filtering before introducing my own aunt to dating over 50 via the Sequel app on the App Store. It is a wonderfully calm, respectful environment designed specifically for older adults, which completely eliminates the fast-paced, meat-market vibe of standard apps. Their manual human review process screens out fake accounts before they can even message anyone, which gave us immense peace of mind. She found it very intuitive to use and is currently enjoying genuine, safe conversations with some highly respectful people.
