Tomorrow Google decides that they are going to do IP based filtering, on spam sites... ... and you switch web hosts? In, like, a day? ... or buy a static IP? ... and/or you and every other customer of webfaction.com threatens to switch, whereupon webfaction.com, faced with wholesale erosion of their business, gets medieval on the "spam sites" and Google forgives them? I appreciate that this would be a major expense and hassle if it happened very often. But (a) this is still a hypothetical example: does Google actually do this? And (b) if this keeps on happening to you, you need to re-evaluate your methodology for choosing web hosts. :)
