Tekken producer fed up with requests for Smash Bros. Ultimate cameos, says devs don't "negotiate with spammers and terrorists"

Katsuhiro Harada, the producer of the Tekken series, is getting quite annoyed with requests on Twitter about various characters appearing in Smash Bros. Ultimate. As a matter of fact, Harada's been so angered by these requests that he said he's specifically telling Masahiro Sakurai not to consider characters for Smash Bros. Ultimate. You can see the two tweets Harada made about the situation below.

I'm honestly a bit baffled by this. I understand that sometimes people can be rude with their requests and spam things over and over again on Twitter, but there can also be legitimate fans who are reaching out due to genuine interest. I'm not sure how far things have gone with the various people called out in Harada's tweet, but I guess the harassment was bad enough in his eyes to make a public comment.
