Looks like there is an artist who goes by "Asphyxiation." Unfortunately that means we've got images depicting asphyxiation with an artist tag on them. If someone else wouldn't mind browsing through and separating the ones where it's the act and the ones where it's the artist, changing that to the tag "asphyxiation_(artist)" I'd appreciate it. Only about 30 pictures, but I'm trying to get bondage wrapped up (pardon the pun, that was truly unintentional) before I dive into anything else. Thanks.
