The task requires filling in the blanks to form coherent sentences. Based on common English usage and context:

1. The first blank likely refers to a type of behavior that is problematic. A fitting word is antisocial.
2. The second blank needs a word to describe a movement opposing vandalism. anti-vandalism or campaign would fit. Given the context of 'movement against vandalism', anti-vandalism is more specific.
