With regards to predatory conferences, I’m wondering if the conferences hosted by the organisation named Inter-Disciplinary.Net in the UK may be dubious:
http://www.inter-disciplinary.net/critical-issues/ethos/space-and-place/
http://www.inter-disciplinary.net/critical-issues/ethos/space-and-place/call-for-papers/
Each participant is expected to pay £297 for the attendance in the conference, which is nowhere mentioned in the call for papers.
They do a whole host of other activities as well, including publishing (under Inter-Disciplinary Press). Perhaps you can take a look into them?
