You can tell her but she probably won’t listen. It’s the Dunning-Kruger effect. People who are the least skilled tend to overestimate their abilities whereas people with more knowledge are able to realize that there’s a lot they don’t know.
Maybe post some links to REAL photographers on her page in the comments section lol. I’m naive enough to think that these fauxs will be humbled once they see some real photography. I almost became a faux when I first started out because I allowed the “OMG you’re so amazing!!” comments to get to my head a little. However, looking at some REAL photography immediately knocked some sense back into me and prompted me to delete my fauxtos from the internets.
