Invitation to take part in "Global", "International", and "Worldwide" conferences seem attractive and prestigious and often with affiliation in Europe, USA, Japan or other well-developed Asia countries.

A broad range of submissions, low processing fees, increasing authors' citations, high "local" impact factor, an invitation to write an article for money, "gift-authorship”, suboptimal author guidelines or special offers.
