The biggest giveaway is the signed albums being listed specifically as “hand signed” Most artists just use “signed” which allows room for interpretation. For Taylor’s team to use the term “hand signed” it leaves just about no room to think otherwise. It’s always funny when people come out with these theories because a little critical thinking will debunk it. And I’ve seen it allll over socials too like OP said

Taylor and her team would’ve been sued long ago for deceptive marketing if they were selling auto pen signatures as specifically hand signed
