I know how you feel
. I go through the same process when trying to figure out where my views come from.
However, though I have mixed feelings about this as well, I usually try to find whoever shared my videos so I can say thanks. Of course, if one website shares a video, then others will also follow suit, and sometimes, as has been noted, credit isn't given. It's a little frustrating, but I figure all that I have to do is pop in and say thanks, and then my name is linked to the share (for SEO purposes, I suppose).
Of course, it would be beneficial to know who's shared a video in real time. Sometimes people ask questions in the comments sections of the sharing website that I would prefer to answer ASAP rather than later and miss out on an opportunity to link up with someone who is interested in what I do. I wish it were possible to see, through YouTube's alert system, where my videos have been shared!
I usually add a few tags in Japanese in my videos as well, but that leads to my videos being shared on random Chinese websites sometimes. I've also seen my videos come up on websites from all kinds of other countries.
While I don't really mind it, I'm genuinely curious as to what those websites have to gain that seemingly automatically post other peoples' videos without very much info. This seems to be a trend in just about every language now-a-days.
Re: Annotations
I always try to put basic info as a text overlay at the beginning of my videos. Of course I also add annotations through YouTube's system as well. I'm starting to play with the idea of adding, as a water mark, basic info on the lower left throughout my videos.
Speaking of watermarks, have you thought of using your YouTube avatar as a watermark on your videos? I forget how many, but after a certain number of subs that becomes an available feature and I think it's to help your 'brand recognition' (or help prevent piracy). I really think that should be available for anyone on YouTube.
IMO this is a very important issue. Thanks for bringing it up Sacred Synthesis! I'm hoping to learn a few things from this thread
