I should also check if "kat" is a common name in their community or if there's a specific person known by that name. It's possible that this is a tribute or a shoutout. The combination of the date and the usernames might be part of a series of posts where they feature different creators or their works.
Putting it together, maybe this is a social media post from 2008, mentioning someone named Kat with the username makekatpurrrr, and "worked from best" could be a hashtag or part of their profile. But 2008 is quite long ago, so maybe the numbers are a different date format. Wait, 22/12/08 would be December 22, 2008. That does make sense as a date.
Alternatively, "worked from best" might be a tag or part of a hashtag that's used to denote that the content is the best work. Maybe it's part of a fan page or a tribute. Also, "inkedpov" might be the creator of this post, referencing someone named Kat through the handle makekatpurrrr, and highlighting their best work from that date.
