Someone, somewhere, probably more than one person, has created a robot that automatically registers to Plone sites and uploads a pile of spam and porn links to the member page.

These are usually easy for me to recognise. I've just gone through the list of members and deleted several hundred of these phony members.

If your account on the site was caught up in the purge, I'm very sorry. Unfortunately I can't just restore your membership - you'll have to re-register.

Hopefully soon this site will be upgraded soon to a newer version of Plone, with moderated membership.
