Just wondering because she seems like everyone’s favorite rare type. You see someone even poke a Sanae, the comments start crying foul. It’s actually kinda funny to see hardcore abyusers holding their hands in a prayer for a Sanae not to get harmed.
Cuz she's rare? Of all common rare type (woah, an oxymoron), she's the most well-known, so ofc abusers would spare her, after all, why should we aim for a rare type when a common type is sufficient? Also, rare type usually are more obedient than common type, so what is the fun of abusing something like that?
Moreover, I think it's also a general concept. About common types (especially wasa, even though it doesn't do anything bad, people still hope for it getting abused, myself include, shame) is notorious for being abuse, so when a good/normal common yukkuri get abused, people complain but not that much because they are used to that. But when a rare type get abused, because not a lot of us know about abusing rare type, which combine with the above thing I mention, will result in what you see and ask.
This isy two-cents, hope it explain something to you.
