I'm getting paranoid, ...
It seems that I'm receiving penalty for accessing specific groups through Google.
Preconditions: 1. China. 2. I'm using ADSL dial-up, everytime I redial, my IP changes.
Symptom: Everything is fine, then I read one article from comp.answers, everything is still fine, then I try to read another article from comp.answers, then I can't get anything from Google groups, at all. Then I go offline and redial, the symptom repeats itself.
Everything, I mean, to read articles from comp.lang.scheme, comp.compilers, etc..
Admitted, I'm getting paranoid now. Maybe totally unreasonable. You know, something in life is for a good laugh, you have many and many good reasons to get serious, but you have the best reason to get a laugh.
