I've never been more proud to be on 4chan.
Never have I been so disgusted by this "anonymous" organization and confused about somebody actually saying they are proud to be on 4Chan.
I don't quite know why but 4Chan scares me.
If it scares you, then learn computer science through and through, and -- probably more importantly -- get to know people and how they think and interact with each other really well. That's something that goes beyond studying some psychology and sociology. It often means putting aside the ideological and "moral" nonsense society has artificially imposed on you and questioning your real motives honestly and purely in a way that can become scary and disgusting at times, then applying that same sort of process while imagining yourself in other people's positions.
Whenever you read someone else's account of their own experience, you can then apply that sort of process and start picking apart what really might have been going on in their heads. Ask yourself, "What would I
not write in their position." Even just hanging out with your friends, take some time to pay attention to everything they do and say and try to figure them out from their perspective.
When you can start to get into people's heads, and you know how to bring down Internet sites and entire computer networks without much trouble, you'll stop fearing things like anonymous mobs from some Internet site.
But for right now, just know that everything you post on the Internet (or even put on a networked computer), is at risk of being copied, modified, and used for all sorts of ill-intended purposes. No authentication system is perfect, so every account and profile you have -- especially with weak or compromised passwords -- can easily be hacked and modified. Even without going that far, any system where others can associate things (like other profiles as "friends") with you is a liability.
Even your Google searches are all saved, and if you have a gmail account (which doubles as a Google account), they're usually saved in the Google Web History under that account. As such, anyone who can get into that can see what you've been searching for.
So with that in mind, try to tread more lightly on the Internet.
