28.05.09 UPDATE: After a bit of tinkering under the hood I hope to have abated the nefarious spam jiggery-pokery. I also have a shiny new install of wordpress, which is really quite impressive! I’m not too sure how the nerdowells got in but hopefully I can keep them out now.
27.05.09: So, I just found that a bunch of links (for things I really don’t want to link to!) were being appended to the posts on this site that came through from del.icio.us in the last month or so. I may halt that bookmark sharing to here for a while, if anyone has had experience of this issue and got to the bottom of it please let me know. Thanks!
