hello and request for advice hi shalom thanks for the post on my talk page when i joined much appreciated i was just wondering about procedures around dealing with persistent spammers i've been watching penetration test computer forensics and pci dss for a while now and they've been plagued by linkspamming particularly penetration test which has repeatedly had its content shaved down and links inserted into it anyway this all comes from one ip address and it ties back to the company which the links are pointing to can anything be done about this it seems harsh to ban them entirely i can't even guarantee the user knows how to look at the talk page associated with his her ip address any thoughts also i note that my attempt to copy the warning stuff into his talk page a few weeks ago was a bit clumsy
