A lesson of CAUTION
It is said, that most women have at least experiences some form of stalking in their life at least once. And think about it, you might find out you've been at some point a victim of stalking as well. Although it may seem flattering at some points, it can also be quite rattling and down right scary.
2. The untraceable name
Kuri curry? Who?
I made my pseudonym due to the fear of being once again stalked. At school, I never imagined I'd actually be stalked up to the point that I was afraid to GO TO SCHOOL. They would watch me go to class almost daily. (That's why I was fairly sure they were there for me) take pictures of me while I'm at Chem Lab, or basically just even follow me up to my house.
There were even points wherein I was approached and followed in a mall up to the point I went to the comfort room. Wherein the guy could no longer follow.
I was afraid, and I DO NOT LIKE being afraid. I did not understand why I was being followed and I did not like it. I usually commute and it's rather hard to be taken seriously if they tag my name with the words, "Ahh the cosplayer?". Outside of my hobby, I'd like to be treated like a professional. Sure, I do tell some of my work mates but with being known as 'the cosplayer' in the office. (You get a LOT of unnecessary attention plus people think you LEND OUT EVERYTHING)
3. Controlling what's shared
Either with settings, or securing that you only post things you want to be seen by EVERYONE on a certain account is a good way to lessen the amount of information people can get their hands on.
With this name of mine, I can control what people see and what they don't. I don't want future clients looking at me and merely seeing that I'm a delusional 'kid' who still fantasizes about old world vampires, mech, and time leaps.
Things that I would suggest NOT being specific about in regards of ONLINE Accounts/Online contests (UNLESS they WILL NOT divulge your private information):
Famous people can do these things, because well for one they have SECURITY. As normal folk, we have a lot more vulnerability then they do. If they or anyone messes with them, it's easier to trace.
Sum it up?
TAKE CARE OF YOUR IDENTITY.
You don't need to bare all to the point that people can make fake accounts in your name and fill up the info section like some well studied for exam.
