Next time i will ask them if a screenshot is sufficient. When the spam is e-mail the ask for the header. But there is no header i guess at blog spam. Thanks for the support Greg. Cheers!
i surf to whois.net and enter the ipadres of the spammer. Then i send a mail to the abuse emailadres of the hosting provider from the ipadres of the spammer. They ask me for a log file. Where can i find the log file from the spam i receive?
