Of course it's unethical, but it would bother me considerably more if they were being sold (as has happened to collections of rare scanned music). Is there any way you can run checks on and/or terminate bulk downloads via single IPs? Apart from anything else, it can't be good to have abnormal amounts of data transferred via your servers.
I think that was tried in the past, but unsuccessful. I'll need to have a look at the statistics.
It may be impolite but it isn't really even unethical, given the grounds on which we post our files.
yeah, point taken. Given that he doesn't make any money of it (or so I assume, the vids are not monetized as far as I could see) it's not fundamentally different from Facebook sharing or retweeting.
