I see, they are organizing too many conferences each year, conference fee is very high, and proceedings too promising. Maybe someone know's World Academy closer?
Yes, a huge number of conferences and each seems to have many unrelated tracts. It does seem like a huge grab for money. I say this in part because there is no link to any past conferences where you can examine the types and quality of the papers and participants. Also, the cost is not clear, you have to register to get costs apparently. And since World Academy...... is considered a Predatory Publisher it is of great concern. I emailed a Canadian faculty member who is on their "advisor list" and will let you know if he responds.
