Suggestions: Possible abuse of resources...

Lets talk just about bandwith abuse at this moment, comment and account spam is another thing.
Now as far as I know you can hotlink almost anything hosted on my.opera personal space.. and that means that you can send a link to a friend but that also means that you can put a clip or a big zip or simply hires image couple of MB big and hotlink it from any other page and simply parasite from Opera's resources... and ok.. that is fine until it is resonable amout of resources... but there is 300 MB of space and ways of abuse are unlimited...
Just few examples:
1. Upload 10 MB clip (funny video), hotlink it from an outside blog, submit it to few fun portals and you will have lets say 50 000 or 100 000 views of that video a day. That means 1 TB of bandwith would be killed in a day... or link usage would be (1 000 000 x 8 / 86400) ~ 9.23 Mbit per second..
2. Upload 1.5 MB HiRes scan of some magazine photo.. upload 6 pics as an example of a photo shoot ... 9 MB total make a post on your forum or blog, submit it to couple of portals and blogs.. if approved that would get you approrx 20 000 - 30 000 unique visits = 270 GB daily or 3.125 Mbit per second.
3. Upload 25 MB zip / rar ... lets say demo album or legal or illegal music.. post it on few warez portals and it will get you 20 000 - 30 000 unique visits a day ... to cut the crap another 750 GB of bandwith or 8.68 Mbit.
etc
Ok.. some of these stuff are legal usage of my.opera space, some are not.. still.. all are possible to qet out with...
I don't know how big link my.opera's servers have and what kind of abuse they can handle (from what I've seen lately, they can't handle normal everyday use) but these stuff are something you should try fighting against.
For example.. you can upload a huge zip (tested yesteday) full of images for your photo album, than manually collect links and hotlink them from other place... why not try to make some sort of hotlink protection in folders album uses for storing files at least? I know there could be issues with refferer since some browsers including opera can block it and some firewalls can do it too.. but there must be a way of making it work...
Also.. why not implementing page with capcha for downloading files bigger than 1 MB from my.opera files... also maybe put on that page "report illegal content" or something like that... hotlinking videos results as a redirect to a page where that video can be viewed but from my.opera.com not some other page... and so on...
Anyhow this is a very serious thing, and I really believe that it should be on a to-do list for my.opera dev's;)
