Is AUTHOR wrong in the post ? POST : My sister and I are identical twins. We've recently been recommended to use Tinder by a friend and we're talking about setting up our profiles. 

I thought of something that to me sounded like it would be funny: We can use each other's pictures for our profiles. Since we're identical, same physical shape included (she has slightly shorter hair and some tattoos, but the tattoos aren't visible), I thought it would be harmless. If someone messaged us seriously, we'd send them our own pictures and be able to let them in on the joke. I also thought it would be a good way to see who enjoys it and has the same sense of humor as us, too.

Another friend didn't think it was that funny, though. He says it's catfishing and we shouldn't be doing that kind of stuff, because even if we're identical twins, we aren't the same person. He says we'll still be lying to people. Any amount of pretending to be someone else is wrong, no matter how 'harmless' we might think it is.

I'll admit, we brushed him off at first, but I've been sitting here thinking about it now for a little and I see his point. I've seen all the stuff about catfishing going around and guys get stung by it a lot. 

I don't want to be that kind of person...but I also don't think this will make me that kind of person. Obviously if conversations go beyond bland hookup requests, we'll come clean.

WIBTA for going through with it?
