This article was posted only an hour or so ago on Eurodressage.
I'm not sure how many people are followers of this website, but I've never seen any sort of direct insult or "slandering" towards Anky or Sjef - and this is honest, I can't even think of one thing I've read in the last two years (that is written by Eurodressage writers themselves) that is against any rider (not even in the Power and Paint articles was a rider slandered by Eurodressage writers).
I've read direct statements given by Sjef (as he is probably the most vocal on defending the subject) and others on the subject, and images of not only Anky's horses, but many horses ridden in rollkür. But no bias throws from the writers themselves.
I do not see any merit for verbal assault other than some sour grapes about the ban of rollkür in warm-up.
