حملة مصر كبيرة عليك

Today I read in Almesryoon webpage that the Police chased those who tried to put the signs of the new campaign of مصر كبيرة عليك next to Gamal posters and .... I wondered why they are posting new signs and paying money for that ... Can not they just use paint or pen or ... to make fun of the original poster? Would not that be faster and cheaper?
