Home Forums Networks & Cross-Platform Networking Spam problems

I've been using gmail for just under a year. I was impressed by the virtually total lack of spam creeping through (unlike other web-based email).
Recently there has been a dramatic increase in this type of traffic (which at least gets routed to the Spam folder).
Whereas for many months I would get no or maybe 1 piece of spam [per month!], as of late this has increased to 1 or 2 per day (usually of the Rx or genitalia-enhancing variety).
Trying to create a filter to eliminate same is unsuccessful because the originating addresses are spoofed. And trying to get a response from the gmail support team is fruitless.
Any suggestions?
