Today I got the questionable "invitation" as a speaker:
"We recently came across your contribution entitled "Liquid Biopsy and Primary Brain Tumors" in the scientific community and thought your expertise would be an excellent fit for Cancer Webinar 2022."
This refers to my paper published just two days ago:

There seem to be a few scientists mentioned on the "Organizing committee", but the topic appears to me too general, so I think this is only a questionable conference not organized by a university or similar institution, especially when "invitation" finally means I should pay for it, even as a speaker.
Or do I get anything wrong here?
