The norm on Lush to spot a fake profile seems to perform a reverse image search on Google.
Now here's a fun challenge for you: are these pictures real or fake?


Google didn't return any result, huh? Surely they must be authentic? Bullshit!
I simply performed some minor modifications on these so that Google couldn't detect the original pictures; I could easily create a fake profile with a complete gallery featuring the same hot guy/girl, and none of the pictures would return any result from Google.
I've been doing these random tests in the last few days and thought I'd share this knowledge with my fellow Lushies. Don't accept a profile as authentic just because Google didn't return any result; pretending to be someone else is extremely easy on the internutz.
And please, refrain from accusing me of 'stating the obvious'. There are actually people here who care about interacting with genuine persons (myself included), even if that's on a purely friendly level. I'm also quite concerned about young girls who could potentially send compromising pictures of themselves to individuals pretending to be someone else.
