If they are a group with big fanbase like Army, Blink or any group from the Big4, I can totally understand why. Those groups have a large number of fans, of course there will be a lot of toxicity going on inside the fanbase. But, the strange thing is, Loona is not even a big group. Their fans are arguably smaller but much louder than fans of more popular groups like Svt and Mamamoo for example. They are on the same level as fromis 9 and it is very rare to hear flover trolling anyone or that loud. However, orbits become trolls on social media, especially Twitter that everyone hate even more than Army and Blink, which is quite surprising.
And many of them actually very insensitive and rude but they thought they're funny by doing that. The question is, how loona can attract such people as fans and dominating their whole fanbase? Like, why mean people like Loona I can say if it's make it more clear. Poor those girls. The proof is that even in front of their own idols, orbits are still unethical and rude. I've honestly never seen idols leave the stage because of fans' behavior like this.
