If you need to assist your personal will power, then add custom CSS to just hide such (or force a smaller font or something).

For all to wit - not a reply to tye's node, but an addendum to his post -this CSS snippet hides post bodies of that insane monk e.g. shmem you want to ignore (510280 is the node_id of my homenode):

<style>
/* shmem */
`[class$="510280"], `[class$="510280"] *, `[class$="510280"]  :link, `
+[class$="510280"]  :visited { display: none !important; }
a`[href$="=510280"]:before { content: "the annoying jerk "; }
</style>

To ignore me, copy and paste that into your Free Nodelet Settings. To ignore someone else, get their homenode id and s///g as appropriate.

update: Added "`" before any [ and inserted <style> tags
