I don’t know of any reason not to link to a non-porn video. People link to videos all the time, in fact. And they even link to videos that violate copyright, which happens all the time on youtube, although your link does not appear to be an example of it. It’s polite to warn people that the link goes to a video, though, for those at work or with slow connections.
Vision, please note that Expano is not a moderator, so what he thinks about board policy is his opinion and not official.
Having said that, I now confirm what he said in this case. I just want to be sure we’re all clear that opinions offered by members are not the same as statements by moderators.
