Ichibrosan Posted June 5, 2013 Share Posted June 5, 2013 I am here today because I have seen the darker side of SpamCop. As the previous owner of a fairly large IP block, I have been receiving SpamCop reports and threats from an end-user. Since the transfer of my IP assets at ARIN took place a while back, I was surprised that I was receiving the reports. I went to the ARIN.NET site and looked up the IP numbers in question, and my email address was not among the POCs associated with the block. Upon further investigation, I found that the reports were being sent to me because of cached POC data at SpamCop. I understand why some caching is advantageous. If a high frequency spam source is operating, querying ARIN in real-time for each message would place a huge load on ARIN's database servers. In my case, an end user contacted me personally by email and threatened to mail bomb me until I brought the spam source under control. This was unfortunate because once I had contacted the new owners of the block about the reported problem, I had no further recourse. This end-user is now very unhappy with me, and it is not my fault. The SpamCop system told him I was the point of contact for the range of IP numbers involved. I don't know how to resolve this "cache" problem, except to suggest that the POC cache should invalidate on a periodic basis, and certainly no less often than daily IMHO.
