I've been using the extremely useful Contact Form 7 plugin for 6 months now. And been using Akismet very sucessfully to block spam, as per this article for 3 months.
Though, suddenly, last night lots of spam messages are now arriving.
Akismet Version 2.5.3
Contact Form 7 Version 2.4.2
I've tested the forms by using 'viagra-test-123' in name field, as per
http://akismet.com/development/api/#comment-check. It was successfully blocked.
Nothing else has changed that I know about...so, I'm a bit stuck really.
Wondered if anyone had any ideas? thx
