The gravatar of Ian Ringrose is also wrong.
Strangely enough the other profile images seem okay, although in an earlier report Last entry in newsletter has messed-up user links, gravatars there are also gravatars wrong.
I checked my email history and in December 2017 this didn't seem to occur for the newsletters received back then. Can this be investigated to confirm if this is yet another quirk of Gravatar or maybe a regression due to the newsletter overhaul that took place in January?
