Time for a proper Firewall...
An AC asked about "an Adblock Plus + filterset.g + customize for PS3?"
Not for the console, no, but instead of plugging your console straight into the 'net, plug it into a spare computer set up as a Firewall.
There are tools for Windows & Linux that allow you to determine the location your system is attempting to connect with.
If you can determine the game is at "game.sony.com" but the ads are coming from "ads.adserver.scumco.com", block "ads.adserver.scumco.com".
Then you never see ads from that server again & problem solved.
Dear Console Makers & Video Game Makers for them.
If I have to spend multiple hundreds of dollars to purchase one of your consoles in order to drop another fifty or hundred to purchase the game, too, then I *Absolutely* *Do* *Not* want to see ads.
You've already GOT my money, so stop wasting my time (& the internet connection I'm paying for) trying to annoy me with ads.
I will do everything in my power to stop you, and there's not a [CENSORED] thing you can do about it.
Want me to watch your ads in a specific game?
Then give me the game for free.
Want me to watch ads in ALL of your games?
Then I want the console gratis as well.
I drop $20K on a new car, I don't expect to get ads flashed across the windshield to "subsidize your manufacturing costs".
I drop $500 on a new game console, I don't expect ads there, either (for the exact same reason).
If I have to pay full price for the console/game, then I'm NOT paying to subsidize those bits.
If you want to show us ads, then you need to SIGNIFICANTLY drop the prices on the console/games to compensate us for our time, bandwidth, & annoyance.
