Spam My Expiring Domain?

I have tried to sell a website i built, but despite my efforts to promote it to companies who would be interested no one has bought it, and the people who seemed interested ghost me after inquiring. It is only valuable to someone in the same state. But I fear as soon as it expires someone will pick it up for cheap and benefit from all my previous work (backlinks, etc) so I want to nuke the domain with spam so no one wants it. It is up for expiration now. Who can help me with that?

why dont you just extend it for another year and see if you can sell it then? or use it for something after alll it seems you put some work into it...don't really see the point to "nuke" it. either you keep it, or if not, well you didn't want to renew it, so whats the point in destroying it?

indeed, just extend the domain's lifetime to 3-4 more years. That will teach those opportunists either to contact you to buy the domain, or quit playing tricks with you.
