It's always nice to see where your work ends up but with stock photography things can get really awkward sometimes. A few months ago I had a friend pose for a series of portraits that I then used in my stock portfolio. She was happy to sign the release after I explained to her that I can't control where the photos end up but she was still caught by surprise when a friend texted her this screenshot and a "OMG, you are on Tinder?!"

She, of course explained what had happened and we had a good laugh about it when she told me but it brought up the eternal issue with stock photography: In order to avoid angry messages from disgruntled models, you need to explain that their photos could end up pretty much anywhere (within reason and the law). It's an example I now use a lot when talking to people about signing a model release (along that of my husband who ended up in an article titled "Reasons women are ashamed of their romantic partners")
