You might want to even consider mentioning the lack of a picture - not in an accusatory manner, but an direct simple statement, like, “I was hesitant about emailing someone without a picture, but I’m surprised by the fact that someone else likes badminton!
However, remember in the early days of the Internet, people did online dating without pictures at all!
And also remember that your “common sense” alarm should be on at all times - whether a profile raises a red flag or not.
Employing a little common sense can help guide you smoothly through even the strangest of profiles.
So let’s say you’re perusing an online dating site, looking at profiles. While profiles without pictures are increasingly rare, they do still exist.
One catches your eye - this person has many of the same, uncommon interests you do, and seems funny and engaging. There’s just one problem: they don’t have a profile picture. There are many legitimate reasons to not want your picture out on the internet, including sensitive job matters.
