Subliminal advertising? I don't get any ads on Rewardia. Maybe it's because I'm on Linux OS?

The advertisers try each kind of trick to get you to look at their advert. Flashing or moving adverts are to get your attention more than not flashing or moving ones. People will try anything to get you to buy their products. I lot of experimenting is going on in the advertising market to draw your attention & hopefully it will brain wash you to go and buy their product goods. It is designed to make you remember in your memory subconscious area of your brain. They don't care if it gives you migraine headaches. All they want is your hard earned cash. Beware!
