That may be because you aren't really supposed to publish someone's work without permission.
Of course people do sometimes post poems here, usually if there is a discussion about them or they are not in print. Odd things are known to happen, and I for one, do not condone them!
A better idea might be to go buy Dangling in the Tournefortia, and read "sick" on page 23. There are many very good poems in that book. You won't regret pulling some money out of your pocket and buying it.
You are right, of course, but this is a group dedicated to the writings of Charles Bukowski, so it is natural that we would not want to infringe on his copyright. Fair Use is a different matter, as mjp said and full poems are posted here reguarly when being discussed, but not in an effort to let anyone avoid buying the book.
He had copyright for a reason. If he did not give a shit about copyright, he would have refused it like d.a. levy did. To answer your question, yes, I think that Bukowksi gave a big fucking shit about seeing that his rights were protected and that his widow was taken care of.
You are not the first person on this forum to think that they knew what Bukowski would want and it always involves something like this.
Also, yes, we know that Bukowski would hate this forum and everyone of us on it.
