Emma - suspect Ian is still on holiday and that the installed spam blocking filter is not perfect - the posters of this sort of material (and eg the get rich quick variety) dont actually check where they post but just use one of the readily available email address scavengers - I once complained about one website blatently copying my material and for my troubles was attached to a pornographic spam emailing 'service' - at least we are saved that - save annoyance for those cases where you can make some difference and pressurise your ISP (at one time AOL used be be a main supplier though recently they seem to have tightened up)to stop such spam/scam mail - it is possible technically but might impinge on profits
