One thing to check for the Username bit is to make sure you've got it right. The name displayed in forums doesn't always match the username. For instance, if you wanted to ignore Pumaman, you'd have to ignore CJ as that's the username listed on his profile.
There shouldn't be any browser-related difficulty with this, but you might try an alternative if you're desperate to rid yourself of PM's by this person (e.g. using Internet Explorer if you're using Firefox, etc.).
I tested mine on Internet Explorer (PC), Firefox (PC), Safari (Mac) and Camino (Mac). No problems every time. I just input the user name (lower-case, incidentally), clicked change profile and it stayed (but with corrected capitalization). Quite convenient as I was able to ignore Farlander on multiple OSes and browsers.
If it still doesn't work, you might try wishing. It's always worth a shot. I agree on the games database. It's amazingly useful but easily abused and not easily fixed up.
