Recently I've discovered by accident that there is a lot of porn and nudity on youtube. I've been doing an experiment. I've made a list of keywords that get a lot of porn and nudity in the search results of youtube. A lot of those get through youtubes content filter. In little more than a week I probably flagged more than a thousand video's. It took me a while to notice a patern:
-new users that post porn get their video's removed and get suspended right away -spammers with followers can upload 100's of video's and don't get suspended for at least a month or two. -there is a category of explicit video's that only perverts watch so nobody flags these. Examples include wet t-shirt contests(often contains full frontal nudity), t-dj's and certain music video's that contain porn. (Some of these had many thousands of viewers). -a lot of porn does not have a descriptive title, a description or keywords. These can only be found via the suggestion bar or playlists.
Please note. I'm not against nudity in a medical or art setting as long as they are age restricted or at least contain a warning(like nsfw). With porn and nudity I mean full frontal nudity and explicit sexual acts, not an exposed butt-crack.
My suggestions for youtube: -make flagging system where you can not only flag a single video, but also a playlist or the uploader. This is an effective way against spammers and nonlisted video's. -video's that contain spamlinks in the desciption get flagged automatically(even if they do not contain porn, they at least contain spam) -use some sort of crc system to detect reuploading of previously removed video's(some users upload the same video 100 times) -make a black list of banned music video's -encourage people to flag video's more
