Not deleting your account wasn't any sort of personal dig at you at all, it's site policy at the moment that we don't delete members following a recent software upgrade. We haven't deleted any accounts since we started the project last December.
I raised the point of deleting spammer, pr0n poster and zero poster accounts some time back with the Admin team and it was decided that we would wait until after we had upgraded the forum to version 3 of phpBB.
We are currently in a test period following the recent upgrade, most things are working as intended, however, we still have a few bugs to iron out.
At the appropriate time, your account will be deleted as per your request, along with all of the other dormant accounts that are currently suspended.
