yeah, sometimes the block eats posts. It's not cencorship or anything. Sometimes the chain isn't 100% perfect.

Ah, OK, so its a known issue then?
I doubt anyone even thought it might be deliberate (censorship) because most of the posts I heard about were regarding contest entries or game entries. In my own case I simply re-submitted and it took the 2nd try.

I just felt it was worth reporting in case it was something not known about.
