Seems targeted, right?
For the last oh, 6 months or so, it has been completely spammed by a few "institutions" which advertise mostly undesirable positions EVERY DAY. It has become an extreme annoyance.
I see these every time I get an e-mail from them. If these were truly desirable positions, they shouldn't have to perpetually advertise for them. Also Vitae should probably cap the number of repeat ads.
