I am wondering if computeroxy can be considered a "safe" website. I have received two emails from them in the past in my institutional email address without subscribing (one of them was a very long list of calls for papers if I recall correctly). Their website has no contact or ownership information other than a simple contact form and an email address, and the whois for their domain name (a .com; not linking to them directly in case they are a scam website) is hidden.
Looking for the name on Google shows some results that seem to support it is a scam but at the same time I do not consider them conclusive.
But today someone I know forwarded a new email from them to the mailing list of a student network. The forwarded message has an enormous list of links to their website with open positions in academia (graduate, postgraduate, senior...) and the non-representative non-random subset I picked had actual real offers (from existing institutions and with links to the offers at the institutions' websites). Since I am part of a team that prepares a newsletter for that student network but reaches a wider audience and includes a section of scholarships and job offers, I was wondering: is it safe to include a link to computeroxy or is it better to just forget about it?
(not quite sure about the tags I have used...)
