WGT doesn't seem to be in any kind of a rush to fix this issue, so I thought I would have a look at it.
I can get some names to appear by temporarily injecting some javascript into the page, but I can't tell if it will work for anyone else.
Anyway, if you know your way around your browsers developer tools and you would like to give this a try, feel free.
Navigate to this forum page...

....then open up your browsers developer tools (on that page), copy the code in blue below, paste it into your browsers dev tools console window and hit enter.
If it works, the page should look like it did before with the last posters username on the page.
It'll all disappear if you refresh the page though because injecting javascript this way is only temporary, and it's still a work in progress.
let lastPost = document.querySelectorAll(".ForumLastPost>a");lastPost.forEach(function(item){fetch(item.href).then(function(response){return response.text()}).then(function(html){let parser = new DOMParser();let doc = parser.parseFromString(html,"text/html");let userName = doc.querySelectorAll(".ForumPostList>li:last-child .ForumPostUserDisplayName>a")[0];item.innerText += " post by ";item.appendChild(userName);})})
Thank you.
