Why can't you just be a good sport, and remove all the data entered by me, and I will go away. It will take you two seconds:
DELETE FROM nodes WHERE username="Logicus";
DELETE FROM nodes WHERE username="simonodell";
Job done... do that and I'm outta here and you have my word I will not be back to bother you.
Continue to insist your going to keep all that data public, and we have a problem, and as long as we have a problem I'm going to continue making it your problem by irritating the hell out of your and your users. You've already declined my offer of dealing with this by a court decision, so your forcing us down this road not me.
