"image generator wants to talk to pyxl.pro"
Followed by a pill-box button that reads: "Sign in with pyxl.pro"
So, it has just occurred to me (I'm a little slow sometimes, getting old) that the sensitivity to one or a handful of "negative" reviews or judgements is enough to flag something potentially important as "spam". It only takes a few (how many, I don't know) "reports" for our automated systems to consider something it is not. (In fact, apparently, a single, probably false, comment suggesting improper jury sequestering could be enough to declare a mis-trial in a recent, high-visibility court case here in the US.)
I'm waiting on results of an important medical test. That's what first drove me to the spam folder in the first place (maybe somehow it was considered spam?).
So, this "hole" in authenticating messages may apply to much more than just vote-related emails. Be careful, and don't assume anything!
