Oh okay… wasn’t sure if the “site” urls were giving you a 404.
If it doesn’t give you a 404 , leave it as-is! If it ain’t broken, don’t fix it
Just checking out your site, it appears the “site” urls do not get redirected, they standalone on their own.
You might want to apply the redirect rules I wrote above, otherwise you’ll have duplicate content. Not a big deal though if you don’t care about that.
New activity stream entries will be correct. Old ones will not.
