how to delete instructables that were entered in contests that are long past?

Hi there,

I just took another read through the terms of service and I feel sort of worried about some of my instructables which could be perceived as hazardous and I would like to delete them.  But because they had been entered in some contests (contests which are long since past) the system won't let me delete them. 

I also tried making them private but got this huge stack trace as a result...

With the ownership changing hands and stuff, I would feel more comfortable deleting some of my old contributions
Thanks for any info
