I greatly value anonymity, and it is for that reason that I find 4chan to be an extremely interesting website.
With that said, I have absolutely no issue with people associating "Pandalink" with me. Heck, I recognise the name "Panda" in real life speech more than my actual name. I don't obsessively try to hide my information because when it comes down to it, if someone really wants to find out about you then they will. I do not, however, post my exact address openly online. That is simply foolish.
If someone like the government was to gain access to my Facebook profile, and was to spend the time to go through all my ~9000 posts on this forum and my dozens of posts elsewhere on the internet under this name, and create a comprehensive file on me or some other shit that people fear when disclosing information online - then they just wasted their time. I would have told them everything anyway if they'd just asked.
Nothing on my Facebook profile is information that I would not give out to someone I recently met.
Similarly, nothing I say on any internet forum is something that I would not repeat in real life.
The same cannot be said of my posts on, for example, 4chan.
