Dear friends of this aggregator

  • Yes, I intentionally removed Newsbud from the aggregator on Mar 22.
  • Newsbud did not block the aggregator, although their editor blocked me on twitter after a comment I made to her
  • As far as I know, the only site that blocks this aggregator is Global Research. I have no idea why!!
  • Please stop recommending Newsbud and Global Research to be added to the aggregator.
