In regards to the DMCA blocks.
I hope you made sure that once posted content is "blocked" due to DMCA complaint,
it is possible for the party posting it to unlock it?
dTube have legal immunity from any sort of claims towards copyrighted content being hosted.
The responsibility lays on the party uploading the content and party claiming to hold copyright.
Then there's Fair Use, and whatever else.
You know what I mean?
