Scott, Most of the questionable listings that are in there are from the original IPswitch list (the yourname.usa one may have been mine). I did my best to sort out as many of the inaccurate ones as I could from the original IPswitch list, but obviously didn't get all of them. I just purged the list of the ones you mentioned though, including all of the xxx.net4dnet.com listings.
By "verify", I mean that I personally, manually added all of the listings that were not on the original IPswitch list. In other words, I went through each individual spam myself, and cut and pasted the domain name directly into the list. It's nowhere near as fast as IPswitch's automated way of culling addresses, but it's a lot more accurate to be sure. Please do let me know if you find anything more that is questionable (that goes for everyone on the list). Like I mentioned, I am pretty conservative myself, and my aim is to have no false positives, rather than being overzealous. I've added a few more listings this morning, and minus the ones I just deleted, there are now 1,867 domains listed. To me, the key to having a good list is keeping it updated frequently. I probably add at least 5 new domains to this list each day or so. At first, it didn't make a huge difference to what was caught, but after awhile it really started adding up.
