Seems like a red flag. I haven't come across this yet personally in online dating but I've heard lots of stories about women using very outdated pictures from when they were younger and hotter. Not sure if that counts as catfishing since it's still the same person, but it's very disingenuous.

It's probably one of the following:

1. She has her own gravitational field pulling in things around her.
2. She's depressed and/or an extreme homebody and doesn't have pictures of herself doing anything for several years.
3. She's self-conscious about her aging.

Yeah. Happens all the time.
