Karl, calm down!
As you can check yourself in our SVN repository, Zeeshan never has been removed from Planet GNOME. Recent changes to the configuration file all were additions. There is no single removal in the log for the last few weeks!
I really start to worry about all the hateress recently seen on Planet GNOME. I am guilty by myself. What happend to the fun? When did we loose our positive spirit? Are our GNOME related day jobs eating it?
Update: But it really seems like Zeeshan's Ubuntu post has been removed from the Planet's cache. I didn't thought this would be possible, but quickly reading over the aggregator's source code revealed that the planet-cache script has a --hide switch for censoring single posts.
So maybe censorship took place. Time for the responsible person to stand up and to explain what append.
Update2: Change the wording of the above update, since so far we just have indications, no proofs.
Update3: Jeff said on IRC that Zeeshan might just have triggered the two-posts-per person limit. Sounds reasonable, so this affair is over for me.
