Because it can be real spam (and then you can use the abuse contact of the resource-holder for the addresses where the spam is coming from), when you report abuse cases, to facilitate the work of the involved parties, you should be allowed to attach or include headers, logs, etc. that probe that it is an abuse (from your perspective).<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;mso-fareast-language:EN-US'>If you filter that, then you will not receive many abuse reports …<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;mso-fareast-language:EN-US'>For example, some abuse mailboxes filter specific URLs or domains.
