Basically it was someone claiming the space as theirs and theirs alone because their contribution was deleted and a ended with a little antisemitism. It seemed to be the same person that was really dedicated to those end rhymes.
I admit I'm responsible for two stanzas with alternating end rhymes which ultimately were kept, the weathervane and Roethke stanzas - which have been edited since, but the rhymes have been preserved. I think people saw the trend and kept it going. It's really the last stanza that it goes overboard for me. Also, geez, talk about someone who couldn't handle the prompt of an editable poem, it sounds like. The whole point is not to get attached to whatever you throw out into the waves. If you like it copy it and keep it.
