For the longest part of my live, especially once I got into the furry community, I learned to embrace the fakeness and effectively lived two lifes: One IRL, one online.
IRL, I was shy, hard to approach, outcasted because i was just..."soooo weird" (read this with your best valley girl accent possible xD)
Online, I had friends, things to talk about and people to talk to most importantly. I also aquired a bit of a status and reputation and quickly found my niche I could slot into and became a mainstay at a certain place - all the things I never had IRL, but which were all based off of a fake personality. Because online, I was not shy and I definitively wouldn't have let anyone tell me that I was weird either. But in the end, it was effectively "fake".
I simply learned to copy some things from online to IRL over the years but it is far from perfect imho.
There is, in my opinion, nothing wrong about embracing the fakeness that anonymity and independence gives you. Maybe this is your way to express your inner self - the one who you really want to be and give that part of yourself a home and place to "exist".
But there are also the fake scammy accounts that nobody wants or needs - though I don't think this is what you are going after here. :)
