Same thing happened to me on tumblr, I had the username “teenager” since 2009 and someone got me deleted after building a following of 350k followers. Social media giants don’t care, 1 we are the product not the consumer 2 there are hundreds of millions who use the product. What does one person mean? I left tumblr for a year, now I’m back on, it’s been a year since I restarted my account under “shouldnt” I have a couple hundred thousand followers so maybe life isn’t that bad. Good luck dude!
