I am Onepoint.
well what do I do...
if I edit a dead link I will leave a copy of the old link in the comments this way someone else can see my work and reconfirm it later on.
If it's a spam-conflict of interest link, I just outright delete it.
Now the area's that I delete the most links are the realtors links to properties
I also place sites that are complaining about other business as a public service. if you don't like that, tell me otherwise I will keep on fixing it until told otherwise
