If you are using chrome as your mobile browser then simply go the top right corner and hit the 3 vertical dots and select request desktop site. It will rid you of the horrible huge screen ads as well as the mobile banners ads that make scrolling practically impossible because it constantly resizes the screen.

Not a perfect solution as you'll have to zoom in to hit buttons to change pages and hitting the last page to enter a thread is obviously more cumbersome but it's better than huge NSFW ads though.
