I also used to show my face when I first started, and I felt completely relaxed about it. I didn't have any family/ friends in London, and the idea of someone finding my profile among thousands of others didn't even cross my mind. After about a year of showing my face on aw, I realised that everybody knows about the website, and my profile is just one click away. I started making friends/ dating, worinkg a part time 'normal' job, and I removed my face shots.
Now I am paranoid about anybody finding me, and the same as Ana30, I crop, blur, retouch everythong that could indicate it's me. I am literally paranoid that someone I know is going to find me, and I am constanly suspicious about texts and emails.
