The description field of your profile on the users site is intended to give you space to describe yourself for supporters that may not know you in real life. It helps them to picture you as a real person, and to have some idea what kind of approvals are safe for you. But of course, this is optional. Use it if it helps. Skip it if it doesn’t. Below are some example descriptions.
My name is Dan. I work at a library, and I love it. I frequently use the computer at work during normal business hours, which are 8am-5pm PST. During those times, I am unlikely to want any filtering at all because . . . (and so on).
I’m a software developer, and I spend a lot of time on the internet for work. I rarely use multimedia sites such as YouTube, and if I do, it is almost always to watch a specific video of educational nature. I mainly want to avoid porn.
I want to avoid all social media from the hours of 8am to 5pm.
I want no images of people on any website, ever.
I find gambling sites tempting and problematic. I want to avoid them.
