Dear Rory,
It is up to the authors’ university to commission an investigation into your claims of potentially falsified data. If the Publisher receives an official note from either the university or the academic editor to retract the paper, the paper will be taken down. Note that MDPI is an adhering member to COPE – the Commission on Publication Ethics – and that we strictly operate according to industry standards. We can not simply retract papers based on blog posts.
Kind regards,
Dietrich Rordorf
