Speak

They said that if you want to be treated politely, then you should treat others with politeness, too. So, Su Yu's fans had to be polite when they speak (comment) so that their Su Yu (A/N: uh, girls (and guys?), Su Yu is Duan Yuan's and not yours – Anti-cp fans: shut up!!!) would not be treated impolitely by the anti-fans. And indeed, the anti-fans are not impolite to Su Yu. Just that, they would teeter to the edge of politeness and impoliteness. And that is by being ambiguous of their words, or words that implies double meaning.
