Indeed. Once free/almost free "generic" top domains emerged like .pro,
.blog, .tech, .design, ... spammers immediately jumped in and started
using them for their wrongdoings. I have a feeling that these domains were
specifically made for their advantage. Immediately I had to adjust spam
settings to make all originating from these go to Junk. It was really
short consideration after which I was quite certain that no serious person
willing to communicate serious matter will use these - not in my book.
