I haven't consciously visited a russian porn site, but I do get lots of e-mails from Russian Ladies wanting to marry me. :-)
I keep on blocking each e-mail and deleting, but the next day another one or two or three arrive. I suspect that they have somehow got my e-mail address and are sending from lots of different PC's that they have managed to access.
Anybody got any idea how to stop it, apart from changing my e-mail address which I am reluctant to do.

I also get the Viagra ones - maybe they think I need it with all the Russian Ladies falling over each other to get at me :-), as well as sofware e-mails (us based) and medicines and watches.

None of them have viruses and I use No-adware which removes any possible intrusive cookies etc.
