It depends on the website. Not because I’m deceptive, but because there are some websites that mandate everything about you reflect yourself and some websites that mandate the exact opposite where you use all made up stuff, along with websites that don’t enforce either one (most websites don’t). Fortunately for me, I happen to have a birth name with many variations (Leni itself is a nickname), another name with a few more, and details about me that fall on certain cusps when trying to categorize them. The name thing is why I often seem to go by different names depending on the website I use. It would also require an explanation to those who wish to see how far my world record goes if I didn’t use wholly matter-of-fact information on the websites I use, as, hypothetically, I would need to verify myself on an external level that I am a certain individual, if that would truly work, since, classically, the verification of the world record comes from all the accounts co-identifying as each other in some way.
