Please be aware of what you say to vtubers
The addition of HoloX is something that should be celebrated, but not in a way that compares the talents. ESPECIALLY not where the vtubers themselves can see it.
There have been Superchats sent to both Lamy and Nene, declaring that "I still love you, but someone else is my new favorite now".
This is obviously UNACCEPTABLE behavior. Lamy was extremely hurt by it, and sending this kind of message to Nene's return stream from mental health problems is another level of maliciousness. It might not have been intended that way, but it sure does read like it.
Be aware that, this is not to say you cannot have new oshis, or that you have to always be dedicated to one person. That is always your personal freedom, but please keep it at that: personal. You do not have to tell everyone else about how you find a new girl better.
Comparing the talents have always been somewhat of a taboo, as it causes discord among the community, but bringing the comparisons to the vtubers themselves far exceeds what even targeted anti attacks can do.
These are not new, and aren't the only examples of damaging behavior.
Some others include :
Constant mentioning of other talents in an unrelated stream;
Talking about another stream in chat;
>"I'm going to watch xxx now, good luck!";
>"I came here from xxx's stream";
Unpleasant comments while including a talent's Egosa words (most talents semi-regularly search their names on Twitter to read about opinions or messages from fans);
And, of course, rude comments and Superchats in general.
Please be mindful of what you say to vtubers, or streamers in general. They are real, living people, and you should act accordingly.
