Thank you for this helpful response. The business practices you name are indeed questionable. Yet its peer review evidently has rigor, it’s in DOAJ, APC is very low compared to the biggies, article typesetting and presentation is good, and I can get my article in PubMed or Ebsco. Since I’m paying my own APC, frankly, $3,000 or so to BMC or PlosOne seems a lot more predatory to me than $100 to ScienceDomain.
It also seems to me, just as maybe a philosophical point, that all the practices that concern you are consistent with the “virtual” presence of an essentially web-based enterprise.
But I am in no way advocating for any change in your assignment of this publisher, given the concerns you have clearly stated. You have every right to your own opinion, and from what I can see you are doing a lot of good by being so strict. Perhaps it is fair to say that ScienceDomain appears to be improving, but has not (yet?) attained sufficient quality or business transparency to be removed from your list.
Thank you again. I appreciate the information very much.
