Is it just me that cant understand why some people feel safe with posting real life pics of themselves on this site? [I Value My Privacy]

So I've joined this site for a while already and I've found out that some people on this site are fine with posting pictures of themselves in real life... not to mention several users here who go as far as to post their own nudes...

I'll be frank but don't you worry about your own privacy? Like don't you worry at all that some people with nefarious motives will take advantage of you via your online photos, especially by using your nudes????
