According to bug 49087, thanks are intended to be private and the only public info about them is "XXX thanked XXX" plus a timestamp, which is at Special:Log/thanks.
Going to https://en.m.wikipedia.org/wiki/Special:UserProfile/MaxSem, I see "Last thanked by Angelo bullet for an edit to Main Page."
The "Main Page" part is not public information.
Version: unspecified
Severity: normal
