User blog:Icecream18/wikia why

wikia w h y

i used to be able to see the comments on a blog by someone who has since changed their username by changing it to their old name in the URL and clicking the redirect but now it doesnt work

how it used to be:

user1234 changed their name to wikilover

wikia.wikia.com/user_blog:user1234/hi

then when they change their account name, it shows no comments

but edit the url to be

wikia.com.com/user_blog:wikilover/hi

and the comments show up

now that doesnt work and it always shows no comments. it used to be like the blog got redirected to the new username but the comments didnt, but now its like the comments are deleted completely.

why

why is this necessary
