When I came here? Not at all. However, I started my writing career on Fanfiction.net, whereas I was so arrogant that I used to unironically compliment myself randomly (OMFG I'm so original and cool), much like this in the middle of my own chapters.
Keep in mind though, I was 12 at the time.
As for ScribbleHub, when I came here, I was legitimately devastated as a person, since my 'Yellow Book', a collection of smut that I'd written over severals years which included paid commissions and the like, was suddenly and without warning, taken down and deleted by an angry admin on Royalroadl, despite me having a screenshot to prove that my story was approved years prior by another admin.
This meant that my source of teenage income was destroyed in a single day and I was pretty much unwilling to build myself up as a porn writer again.
This in turn resulted in me writing something out of the height of my depression, that being my 'Lord Of Horrors', a cringe fest that was thankfully never finished, which you can find here on ScribbleHub as I ran away to this site after that exile from Royalroadl.
..but seriously, don't read it. Apart from like, the psycho twincest smut chapter, the story isn't worth anyone's time.
