Maybe they've been freshly banned and there is some delay occurring before their posts get hidden? There has definitely been a wave of troll posts this week, and resulting bans occurring. World even had to suspend open signups and close a community a few days ago.
Admins don't always choose to purge all posts by a user who has been banned, sometimes they'll just ban the person and remove the infringing posts since if the person was a very active user purging them could take a chunk out of the content on the site, and assuming they have mostly legitimate posts it's probably the best option to remove specific troll posts after banning than to purge their whole profile.
Also if someone is temporarily banned they almost never purge those people since it's a temporary ban, many of the recent bans on LW have been temporary or are long-time members on the site with a lot of content.
That makes sense.
When a user is banned, temporarily or permanently, liftoff shows a banned flair on their name, if they are banned from the community it'll show a banned from community flair. This shows up when the user is banned from the instance you're viewing it on or from their home Instance. When an Instance is defederated it won't show any flare or indicator, at least as of the current version.
