I mentioned TWINTAIL UPLOADER elsewhere because it has some Tenma-chan theme.

I don't think it should be a simple name for the sake of it, because there exists many such uplaoders and afaik they aren't usually referred by the name of those who made it
However "Heyuri Uploader" in this case may be fine too, because Heyuri was originally a file uploading service and not a BBS
