Because I want to help people by advising that they avoid this ridiculous publisher.
My guess is that they (Trade Science) are trying to fill up their journals with content and then they will switch to an author-pays model.
I have examples of spam email from Trade Science that say.
“Maximum publication time 15 days”
and
“Acceptance or rejection of submitted manuscript will be informed within 7 days limit to corresponding author.”
I recommend that people avoid this publisher. It is very suspicious and possibly a big scam.
