Occasionally I get weird comments on my weblog like this one which says “z03a26c291bbe9a3144dc3ca36012f866z Good work, nice webpaqe“. It doesn’t link to any URLs, well - no real ones, so I don’t think its the usual page-rank spam junk which I get bombarded with. Is this a spammer “trying some stuff out” when my spam blocker knocks them back? Thanks to the incorrect spelling of “page” this one is highly googleable, returning about 38K hits on a variety of sites. Another variation seems to be ones like these here which say things like “zb1d232a62f41a9bfbb50aeaad8ece73cz Nice design, good work !“. Anybody have any thoughts about this?
