The worst thing that could happen would be something like this:
If you run a webserver a simple request would give the domain name associated. A whois could then give away your identity. Then a malicious anonymous could spam your name here with a lot of shit (racism, and so on). Now a google search with your name would link you with this place, and you might not be willing to aknowledge you're visiting this shithole.
You could still post anonymously, but you'd have to cope with your name being posted here sometimes (like Xarn).
