As I have stated before here I am the one doing this particular batch of uploads. That said, and speaking as an admin, I have the ability to transfer ownership control of content to a specific account, which I do for all my reuploads of Carpdime’s content. (I do the same for all reuploaded content where the creator has made an account on this site. If they haven’t, they’d be place under Archivist or one of the numerous archive accounts)
If you’re wondering why Carpdime himself has not been reuploading his past content, the reasons are as such: ( a) Carpdime did not save any of the stuff he had previously uploaded to the booru and ( b) he prefers not to upload his past content himself. Also, ( c) I had reach an agreement with him that I can upload his past content, a process which I had decided to do slowly until recently. Part of the reaosn why I did it slowly, and if you’ve noticed, is because I like to research and give as much background as I can about a specific image Carpdime has drawn. I’m a little critical of the way some past booru content has been haphazardly reuploaded.
Lastly, if you’re looking for content Carpdime himself has drawn, it would be content that does not have a fluffybooru ID and is most recent. Here’s an example drawn in March.
