This was a bug that we patched yesterday. Originally, this post basically acted like a zip bomb and the text blew up to be enormously huge to the point that the page often wasn't loading correctly. This user basically found an exploit in PieFed's markdown to html conversion and, instead of disclosing it to the maintainers, made a troll-y post about it that started breaking things.

It is patched now though as of PieFed 1.4.5.
