Re: Identifying spam text

An easy thing to do might be to limit the number of submissions a single IP address can submit in a given period of time. That way, an occasional spam will get through, but its effect will be limited. Also, if this web form has a standard url -- like you got it from a major script site like hotscripts or something -- just changing the url and some of the form names away from the default settings will go a long way towards thwarting a casual spam attacker. Mostly, these types of events seem related to targets of opportunity, so to speak. -- jon -- jon roig web developer phone: 888.230.7557 email: jon@trafficdesigns.com Merlin wrote: > Hi there, > > I am running a community site in php, where members can be contacted > through a web form.
