BUMP.
Stay well away from this guy. We have purchased this module three times over the years (2018 to 2022) and today he has had two of my domains suspended by the webhost as he is claiming copyright infringement out of the blue.
This isn't the first time I've dealt with him. His name is Pierluigi Spaziani. In previous encounters he has gone away after tedious back and forth over email.
