Ah, right - I see now thanks (it didn't occur to me to click 'show nsfw').

As for the 'oejwfiojwwqpofioqwfiowqiofkwqeifjwefwef' - I remember them as being spam. It was maybe a year or so ago now, but a LW user tried creating communities with every name imaginable as way to squat on them. They got to about 2000 before they were stopped, and in retaliation they created about 4000 of the 'wefwef' ones (I guess that the deletion of them from LW didn't make it somewhere, and so something out there still thinks they exist).
